How PPE standards affect employers |
Hard hats, goggles, face shields, steel-toed shoes, safety
glasses, aprons, gloves, coveralls. What do they have in common?
They are all various forms of personal protective equipment (PPE).
The Occupational Safety and Health Administration (OSHA)
standards for PPE are contained in Subpart I of its general industry
standards. These standards were adopted in 1971 from established
federal standards and national consensus standards.
In developing a proposed revision of Subpart I, OSHA performed a
comprehensive review of the PPE standards. The review revealed that:
- Many of the existing PPE standards were outdated, reflecting
knowledge and practices regarding PPE as they existed in the
late 1960s and early 1970s.
- Certain gaps in coverage of the PPE standards existed and the
standards set very restrictive design criteria, limiting the use
of new technology.
- Restraints on innovation made it more difficult for employers
either to increase acceptance of PPE or to provide more
protective PPE.
- Injury data and technical reports showed injuries were
occurring to employees who were wearing PPE as well as employees
who were not wearing PPE. This indicated that, in some cases,
significant improvements in PPE design and acceptance might be
needed.
Updated PPE standards (29 CFR Part 1910) went into effect July 5,
1994 and included:
- 29 CFR 1910.132 General Requirements
- 29 CFR 1910.133 Eye and Face Protection
- 29 CFR 1910.135 Head Protection
- 29 CFR 1910.136 Foot Protection
- 29 CFR 1910.138 Hand Protection
The revised standards address five main areas:
- Current American National Standards Institute (ANSI)
guidelines
- Hazard assessment for each work area
- Use of defective PPE
- Employee training
- Properly fitting PPE
General Requirements
29 CFR 1910.132 requires employers to ensure that PPE be “provided,
used and maintained in a sanitary and reliable condition wherever it
is necessary” to prevent injury. This includes protection of any
part of the body from hazards through absorption, inhalation or
physical contact.
Eye and Face Protection
Employers are required under 29 CFR 1910.133 to provide employees
with suitable eye and face protection where there is reasonable
probability of injury that can be prevented by using such
equipment.
Eye and face devices purchased after July 5, 1994 must comply with
ANSI Z87.1-1989. Equipment purchased prior to July 5, 1994 has to
meet the 1968 standard or be equally effective.
29 CFR 1910.135—Head Protection
Head injuries are caused by falling or flying objects, or by bumping
into a fixed object. Head protection must do two things—resist
penetration and absorb the shock of a blow.
Protective helmets purchased after July 5, 1994 must comply with
ANSI Z89.1-1986. Equipment purchased prior to July 5, 1994 must meet
the 1969 standard or be equally effective.
Foot Protection
29 CFR 1910.136 requires occupational footwear to meet ANSI
specifications. Protective footwear purchased after July 5, 1994
must comply with ANSI Z41-1991. Footwear purchased prior to July 5,
1994 has to meet the 1967 standard or be equally effective.
Hand Protection
29 CFR 1910.138 requires employers to select appropriate hand
protection for employees exposed to hazards such as those from skin
absorption of harmful substances, severe cuts or lacerations, severe
abrasions, punctures, chemical burns, thermal burns and temperature
extremes. Hand protection must be selected relative to the task to
be performed, conditions present, duration of use and any hazards or
potential hazards identified in the hazard assessment.
“Provide?”
In July of 1999, OSHA introduced regulatory language to clarify that—
with only a few exceptions—employers must pay for the PPE
provided. In certain circumstances, three specific kinds of PPE are
exempt from this requirement: safety-toe protective footwear,
prescription safety eyewear and the logging boots required by 29 CFR
1910.266(d)(1)(v).

OSHA begins program to reduce amputations |
The Occupational Safety and Health Administration (OSHA) is
implementing a national emphasis program on preventing amputations
in general industry. The program expands on the existing national
emphasis program* on mechanical power presses.
The program will focus on all types of power presses, shears,
slitters, saws, slicers and press brakes. Employers within industry
Standard Industrial Classification (SIC) codes that have machines
included in the program will be targeted for inspection. Employers
that have had an amputation injury within the past five years will
be targeted as well.
OSHA notes that a project conducted by the National Institute for
Occupational Safety and Health (NIOSH) found that workers who
operate and maintain machinery suffer numerous amputations and more
than 800 deaths occur per year. According to the Bureau of Labor
Statistics, there are more than 10,000 amputations each year.
Each regional and local OSHA office will be responsible for
locating employers in their geographical area that are believed to
have these types of machines or have had amputations or fatalities
involving any of these machines within the past five years. These
employers will be scheduled for a compliance inspection. A
work-place that has had a comprehensive safety inspection in the
previous 24 months will be deleted from the targeted inspection list
(if no amputations occurred). Establishments on the local OSHA
office inspection list will be inspected by random selection.
At the inspection, the compliance officer will inspect every
machine present in the workplace that is included in this special
emphasis program. The inspection will also include reviewing the
OSHA log of injuries and illnesses for amputation injuries or
hazards.
Normally these focused inspections will be limited to hazards
associated with the machine types referenced by this program.
However, a compliance officer may expand the scope of the inspection
beyond these machines if other hazards or apparent violations are
observed during the walk-around or are documented in the OSHA log.

Foot protection basics—what you should know |
Protective footwear is required in many workplaces. The
Occupational Safety and Health Administration (OSHA) states in its
Occupational Foot Protection regulation, 29 CFR 1910.136(a), “Each
affected employee shall wear protective footwear when working in
areas where there is a danger of foot injuries due to falling or
rolling objects, or objects piercing the sole, and where such
employee’s feet are exposed to electrical hazards.”
In terms of what constitutes “pro-tective footwear” under
1910.136(b), OSHA requires that the footwear com-ply with ANSI
Z41(1991), American National Standard for Personal Protection—Protective
Footwear, or shall be demonstrated by the employer to be equally
effective.
Requirements of ANSI Z41-1991
ANSI Z41-1991 defines performance measurements and test methods
for protective footwear. The standard contains performance
measurements for impact and compression protection for the toes,
metatarsal protection for the toes and metatarsal area (top of
foot), electrical hazard protection, conductive protection and
protection against punctures and penetration.
An important point to remember is that the ANSI standard does not
allow for the use of add-on type devices (strap-on foot, toe or
metatarsal guards) as a substitute for protective footwear.
According to part 4.1.1 of the standard, “The toe box shall be
incorporated into the footwear during construction and shall be an
integral part of the footwear.”
While ANSI excludes add-on devices, it doesn’t necessarily mean
they’re not acceptable to OSHA. This paradox exists because OSHA
states under 1910.136(b) that footwear shall comply with ANSI or
shall be demonstrated by the employer to be equally effective. This
means that if an employer can provide documentation, such as testing
data proving their add-on devices provide protection equivalent to
ANSI performance standards, then the add-on devices are acceptable
to OSHA.
Most manufacturers of add-on devices have submitted their
products to independent laboratories for testing. This data can be
obtained from the manufacturer upon request.
Protective footwear can meet all the requirements of the ANSI
standard, or specific elements of it. A steel-toed work boot that
meets the impact and compression requirements of the ANSI standard
may not provide protection for metatarsal, electrical or penetration
hazards. All footwear manufactured to ANSI specifications is marked
with the specific portion of the standard with which it complies.
The ANSI standard incorporates a coding system that manufacturers
use to identify the portions of the standard with which the footwear
complies. The following is an example of an ANSI code that could be
found on footwear:
ANSI Z41 PT 91
F I/75 C/75 MT/75
Cd 1 EH
PR
Line 1: ANSI Z41 PT 91—This line identifies the ANSI
standard. The letters PT indicate the protective toe section of the
standard. This is followed by the last two digits of the year of the
standard with which the footwear complies (1991).
Line 2: F I/75 C/75 MT/75—This line identifies the
applicable gender (M or F) for which the footwear is intended. It
also identifies the existence of impact resistance (I), the impact
resistance rating (75, 50 or 30 foot-pounds), compression resistance
(C) and the compression resistance rating (75, 50 or 30, which
correlates to 2500 lbs., 1750 lbs. and 1000 lbs. of compression
respectively). This line can also include a metatarsal designation
(MT) and rating (75, 50 or 30 foot-pounds).
Lines 3 & 4: Cd 1 EH & PR—This area of the code
designates conductive properties (Cd) and type (1 or 2), electrical
hazard (EH) and puncture resistance (PR), if applicable.
The identification code must be legible (printed, stamped,
stitched) on one of each pair of protective footwear.
All footwear requires routine inspection for cuts, holes, tears,
cracks, worn soles and other damage that could compromise its
protective qualities. Outsoles should be kept free of stones, tacks,
nails and other debris. Footwear should be cleaned according to the
manufacturer’s instructions.
Who needs foot protection?
Appendix B to subpart I of OSHA’s Occupational Foot Protection
regulation identifies the following occupations for which foot
protection should be routinely considered:
- shipping and receiving clerks
- stock handlers and clerks
- carpenters
- electricians
- machinists
- mechanics and repairers
- plumbers
- assemblers
- drywall installers and lathers
- packers
- wrappers
- craters
- punch and stamping press operators
- sawyers
- welders
- laborers
- freight handlers
- gardeners and grounds keepers
- timber cutting and logging workers
- warehouse laborers

Storm water discharges regulated by EPA |
Storm water discharges such as oil and grease from roadways,
pesticides from lawns, sediment from construction sites and
carelessly discarded trash are covered under the Clean Water Act (CWA),
passed in 1972.
The CWA, as amended in 1987, prohibits the discharge of any
pollutant into waters from a point source unless authorized by a
National Pollutant Discharge Elimination System (NPDES) permit. The
Environmental Protection Agency (EPA) has established NPDES
requirements for storm water discharges.
The Phase I storm water rule, issued in 1990, covers medium and
large municipal separate storm sewer systems (MS4s), which include
cities or jurisdictional entities serving populations more than
100,000. In addition, operators of construction activities
disturbing more than five acres and 11 categories of industrial
activities are required to obtain permit coverage.
On Dec. 8, 1999, the EPA issued Phase II of the program, which
extends NPDES permit requirements to small MS4s and construction
activities disturbing more than one acre. Phase II permits become
mandatory March 10, 2003.
Storm water management programs for all regulated small MS4s must
include the following six minimum control measures:
- Public education and outreach
- Public participation and involvement
- Illicit discharge detection and elimination
- Construction site runoff control
- Post-construction runoff control
- Pollution prevention and good housekeeping regulated by EPA
The EPA has published best management practices (BMPs) and
measurable goals for each minimum control measure (EPA Fact Sheet
2.9). These practices serve as guidelines to assist operators of
small MS4s in achieving Phase II requirements.
Fact Sheet and Reference documents concerning the Phase II Final
Rule may be obtained from the EPA Office of Wastewater Management by
calling 202-260-5861 or online at cfpub.epa.gov/npdes.

How to keep teenagers safe at work |
Millions of teens work. These jobs provide benefits to both
employers and teens. Employers get fresh ideas and hard workers,
teens gain valuable experiences. Because these teens will someday be
the adult workforce, it is important that they start out on the
right foot and are kept safe at work.
The Fair Labor Standards Act (FLSA) prohibits teens from
performing tasks determined to be too hazardous. A list of 17
hazardous non-farm jobs considered off limits for teens under the
age of 18 includes:
- Manufacturing or storing explosives.
- Any driving by 16-year-olds; limited driving for
17-year-olds.
- Coal mining.
- Logging and saw milling.
- Power-driven wood-working machines.
- Exposure to radioactive substances and to ionizing
radiation.
- Power-driven hoisting equipment.
- Power-driven metal-forming, punching and shearing
machines.
- Mining, other than coal mining.
- Meat packing or processing (including power-driven meat
slicing machines).
- Power-driven bakery machines, including mixers.
- Power-driven paper-products machines.
- Manufacturing brick, tile and related products.
- Power-driven circular saw, band saws and guillotine
shears.
- Wrecking, demolition and ship-breaking operations.
- Roofing operations.
- Excavation operations.
There are limited exemptions from this list for apprentices and
student-learners under specified standards.
Instruct teens about safety
Stressing safety is vitally important to help eliminate injuries
to teens. Their inexperience counts against them. Employees—including
teens— with less than one year of experience account for almost
one-third of the occupational injuries each year.
To help prepare teens to work safely, follow these simple steps:
- Double check tasks. Most tasks that teens are going to
be asked to do are new experiences for them. Taking the time to
show them how to properly perform a task and then watching them
complete the task can help over-come their inexperience. Also,
allowing teens the opportunity to ask questions freely will
clear up any questions they may have. Check in with teens later
to make sure they are performing the task properly and following
all necessary safety precautions.
- Show teens how to use safety equipment. Although the
FLSA does prohibit teens from performing particularly hazardous
jobs, this does not eliminate all hazards. Be sure teens
understand when and how to use proper safety equipment. They
also need to know about safety rules concerning buildings and
equipment, such as not blocking doors or removing safety guards.
- Prepare teens for emergencies. Every worker in a place
of business needs to be ready in the event of an emergency.
Teens are no exception. They should be trained along with your
regular workers on how to respond to fire, weather or other
potential emergencies. They also need to know who to contact if
an injury should occur, if they need first aid or if they need
medical care.
- If a safety and health program is not in place, set one up.
This is your best defense against workplace injuries and
illnesses. Work with supervisors and experienced workers to
develop an injury and illness prevention program to help
identify and solve safety issues. Make sure teens are included
in this program and in the safety training that goes along with
it.
Other teen employment issues
In addition to following strict safety guidelines with teens, it
is also important to make sure their rights are not violated and
that they are not working more hours than they are allowed. For
this, you need to check your local, state and federal labor laws.
Generally speaking, youths 18 years or older may perform any job,
whether hazardous or not, for unlimited hours in accordance with
minimum wage and overtime requirements. Youths 16 to 17 may perform
any nonhazardous job for unlimited hours. Youths 14 to 15 may work
outside school hours in various nonmanufacturing, nonmining and
nonhazardous jobs up to three hours on a school day, 18 hours in a
school week, eight hours on a non-school day and 40 hours on a
non-school week.
For more information on teens in the workplace, the following

OSHA releases safety manual for metalworking fluids |
In November 2001, the Occupational Safety and Health
Administration (OSHA) released its “Metal-working Fluids: Safety
and Health Best Practices Manual” Directorate of Technical
Support. This manual is intended to assist industries that work with
metalworking fluids and is to be used as a guide—not a regulation
or a standard. It creates no legal obligations. The manual does,
however, pull information from current regulations and applies them
to the metalworking industry.
Metalworking fluids are also known as machining fluids, cutting
fluids or cutting oils. They are used for grinding, cutting, boring,
drilling and turning metals and can generally be found in the
automotive, aircraft, machinery production and hardware production
industries. The primary functions of metal-working fluids are
cooling and lubrication, although they can also provide corrosion
resistance to the machined part and the machining tool.
The manual provides suggestions on how to choose a fluid. OSHA
recommends considering the toxicity of the fluid components, the
flammability of the fluid and the fluid disposal procedures.
The manual also gives information on when a metalworking fluid is
unsafe to use. The fluid may be unsafe to use if it appears
abnormal, i.e. it is foul smelling or foaming, there is floating
matter on the fluid or if oils from other processes are floating on
the surface. If the sump level is low, the machines are dirty or if
the employees are showing signs of skin or respiratory irritation,
the metalworking fluid also may be unsafe.
Potential health effects from metalworking fluids include
irritation of the skin, lungs, eyes, nose and throat. Conditions
such as dermatitis, acne, asthma, hypersensitivity, pneumonitis,
irritation of the upper respiratory tract and a variety of cancers
have also been associated with working with metalworking fluids.
The manual provides information on ways to protect employees from
these health hazards. Engineering and work practice controls—isolation,
ventilation, personal hygiene practices, good housekeeping,
inspection, maintenance procedures and proper supervision— are
discussed. Proper personal protection equipment (PPE) is also
discussed. PPE may include respirators, gloves, eye and face
protection, foot protection or hearing protection.
The following topics are also included in this manual:
- Establishing a Metalworking Fluid Management Program
- Instituting an Exposure Monitoring Program
- Medical monitoring of exposed employees
- Training
- A Self-Assessment Procedure to determine the effectiveness of
an employer’s existing program
For more information on this manual, request Lab Safety Supply EZ
Facts ® document No. 218 at www.labsafety.com
or by fax at 1-800-393-2287. The manual is available in its entirety

Identify and prevent latex allergies in your workplace |
Latex products are manufactured from a milky fluid derived from
the rubber tree,
Hevea brasiliensis. Some proteins in latex can cause a range
of mild to severe allergic reactions and some of the chemicals added
during processing of commercial latex may also cause skin rashes.
Current methods of measurement do not allow easy or consistent
identification of allergy-causing proteins (antigens) or their
concentrations. Therefore, total protein is used as an indicator of
the exposure concern.
Latex allergy can result from repeated exposures to proteins in
natural rubber latex through skin contact or inhalation. Reactions
usually begin within minutes of exposure to latex, but can occur
hours later, produce various symptoms, such as skin rash and
inflammation, respiratory irritation, asthma and—in rare cases—
shock. In some instances, sensitized employees have experienced
severe reactions that impeded their ability to continue working in
their current jobs.
The amount of exposure needed to sensitize individuals to natural
rubber latex is not known, but reductions in exposure to latex
proteins have been reported to be associated with a reduction in
sensitization and symptoms.
People at increased risk for developing a latex allergy include
workers with ongoing latex exposure, people with a tendency to have
multiple allergic conditions and people with spina bifida. Latex
allergy is also associated with allergies to certain foods, such as
avocados, potatoes, bananas, tomatoes, chestnuts, kiwi fruit and
papaya.
Where is latex found?
Many products contain latex: medical supplies, personal
protective equipment and many household objects. Most people who
encounter latex products only through their general use have no
health problems from their use. Usually it is workers who repeatedly
use latex products.
Individuals who already have latex allergy should be aware of
latex containing products that may trigger an allergic reaction.
Types of reactions
Three types of reactions can occur in people using latex
products:
- Irritant contact dermatitis: Though not a true allergy,
this is the most common reaction to latex products— the
development of dry, itchy, irritated areas on the skin, usually
the hands. It’s caused by skin irritation from using gloves
and possibly by exposure to other workplace products and
chemicals. The reaction can also result from repeated hand
washing and drying, incomplete hand drying, use of cleaners and
sanitizers, or exposure to powders added to the gloves.
- Allergic contact dermatitis (delayed hypersensitivity): This
is sometimes called chemical sensitivity dermatitis and results
from exposure to chemicals added to latex during harvesting,
processing or manufacturing. These chemicals can cause skin
reactions similar to those caused by poison ivy. As with poison
ivy, the rash usually begins 24 to 48 hours after contact and
may progress to oozing skin blisters or spread away from the
area of skin touched by the latex.
- Latex allergy (immediate hypersensitivity): This can be
a more serious reaction to latex than irritant contact
dermatitis or allergic contact dermatitis. Certain proteins in
latex may cause sensitization. The amount of exposure needed to
cause sensitization or symptoms is not known, but exposures at
even very low levels can trigger allergic reactions in some
sensitized individuals.
Reactions usually begin within minutes of exposure, but can occur
hours later and can produce various symptoms. Mild reactions involve
skin redness, hives or itching. More severe reactions may involve
respiratory symptoms—runny nose, sneezing, itchy eyes, scratchy
throat and asthma. Rarely, shock may occur; but a life-threatening
reaction is seldom the first sign of latex allergy.
Prevention
The National Institute for Occupational Safety and Health (NIOSH)
recommends selecting products and implementing work practices that
reduce the risk of allergic reactions.
They include:
- Use nonlatex gloves, such as nitrile or vinyl.
- When using latex gloves, choose powder-free gloves with
reduced protein content.
- When wearing latex gloves, do not use oil-based hand creams or
lotions unless they have been shown to reduce latex-related
problems.
- Frequently clean work areas contaminated with latex dust
(upholstery, carpets, ventilation ducts, plenums).
- Frequently change ventilation filters and vacuum bags used in
latex-contaminated areas.
- Learn to recognize the symptoms of latex allergy: skin rashes;
hives; flushing; itching; nasal, eye or sinus symptoms; asthma;
and shock.
- If you develop symptoms of latex allergy, avoid direct contact
with latex gloves and products until you can see a physician
experienced in treating latex allergy.
- If you have latex allergy, consult your physician regarding
the following precautions:
- Avoid contact with latex gloves and products.
- Avoid areas where you might in-hale the powder from latex
gloves worn by others.
- Tell your employers, physicians, nurses and dentists that
you have latex allergy.
- Wear a medical alert bracelet.

Ask a Tech Rep - FALL PROTECTION FACTS |
|
by Amy Hamilton
Technical Representative
|
| Q. |
When did OSHA’s
Construction Fall Protection Standard take effect? |
| A. |
The Construction Fall Protection
Standard (29 CFR 1926, Subpart M) final rule was published on
Aug. 9, 1994. With the exception for steel erection
activities, the effective date was Feb. 6, 1995.
|
| Q. |
What are the strength
requirements for fall arrest system anchors? |
| A. |
Fall arrest system anchors must be
capable of supporting a static load of 5,000 lbs. for every
worker connected to the anchorage, unless engineering
certification exists. Anchorages that have engineering
certification must still maintain a safety factor of at least
2:1 when the system is designed, installed and used under the
supervision of a qualified person. Fall arrest systems must
limit a fall to 6 ft.
|
| Q. |
What are the strength
requirements for positioning device anchors? |
| A. |
Positioning devices must be able
to support at least twice the potential impact load of an
employee’s fall, or 3,000 lbs., whichever is greater. Fall
positioning devices must limit a fall to a maximum of 2 ft. |
| Q. |
What is residential
construction? |
| A. |
OSHA defines residential
construction as work on structures where the working
environment, construction materials, methods and work
procedures are essentially the same as those used for building
typical single family homes and townhouses. Work on discreet
areas of a large commercial structure may also be considered
residential construction as long as the working environment,
method, materials and work procedures are similar to those
used for single family homes and townhouses. This includes
buildings that will not be used for occupied residences, but
for light commercial purposes.
|
| Q. |
Are alternative fall
protection procedures allowed for residential construction? |
| A. |
Yes. When an employer can show
that conventional fall protection is not feasible at a
specific worksite, the employer may implement an “alterna-tive
fall protection plan.” The plan must be in writing, designed
for the specific work site, and specify alternative protective
measures. The fall protection plan must meet the requirements
of paragraph (k) of 1926.502. |

worth noting . . . |
Consultations: OSHA has revised what it calls the “policy
framework” for its consultation program. The agency published a
new compliance directive, which explains that employers in
high-hazard small businesses will be given priority for consultation
visits. Among the changes, the consultation policy requires
employers to post the hazard list they receive following a
consultation visit for either three working days or until any
serious hazards are abated, whichever is later. Agreed-to
modifications or extensions of correction due dates also must be
posted. Additionally, employee participation is now required as part
of all site visits. The directive can be downloaded at www.osha-slc.gov/OshDoc/Directive_pdf/TED_3-6.pdf.
Survey: The Executive Survey of Workplace Safety found that
95 percent of business executives questioned have reported that
workplace safety has a positive impact on a company’s financial
performance. The survey, conducted by Liberty Mutual Insurance Co.,
included interviews with 200 executives responsible for worker’s
compensation at 125 mid-size firms and 75 large companies. Of those
executives, 61 percent said their companies receive a return on
investment (ROI) of $3 or more for every $1 they invest in improving
job safety.
Grills: The U.S. Consumer Product Safety Commission (CPSC)
has developed a new safety standard to prevent the over-filling of
propane tanks for gas grills. This standard is located at www.cpsc.gov/CPSCPUB/PUBS/cpsr_nws21.pdf.
Guide: The NIOSH Pocket Guide to Chemical Hazards (NPG) is
available online. It’s a source of general industrial hygiene
information on several hundred chemicals and classes for workers,
employers and occupational health professionals. The NPG does not
contain an analysis of all pertinent data, but presents key
information and data in abbreviated or tabular form for chemicals or
substance groupings (e.g. cyanides, fluorides, manganese compounds)
that are found in the work environment. The information is intended
to help users recognize and control occupational chemical hazards.
The NPG includes chemical structures and formulas, identification
codes, synonyms, exposure limits, chemical and physical properties,
incompatibilities and reactivities, measurement methods, respirator
selections, signs and symptoms of exposure, and procedures for
emergency treatment. To see the online version of the NPG: www.cdc.gov/niosh/npg/npg.html.
