Purpose: To assess physical, chemical, and light radiation hazards in our work environment and to select and provide appropriate personal protective equipment (PPE) to help prevent injury from these hazards in accordance with OSHA 1910.132.
Notes: Protective equipment alone shall not be relied upon to provide protection against hazards, but will be used in conjunction with guards, engineering controls, and sound safety practices. This plan is not intended to conflict with, but is to address safety concerns not covered by our Respiratory Protection, Lead in Construction, Bloodborne Pathogens, Logging Safety, Confined Space Entry and Laboratory Safety Plans. Questions with regard to specific hazards, levels of risk, and type of PPE should be referred to your supervisor, EH&S, and MSDS’ when appropriate.
HAZARD ASSESSMENTS and REQUIRED PROTECTION
Type of Hazard: Head
Sources: Electrical, Impact, Heat, Chemical
Required Protection: Where falling object hazards are present, protective helmets complying with ANSI Z89.1-1986 are required. Class A helmets will be used to provide electrical protection up to 2200 volts, Class B up to 20,000 volts. Heat, cold and chemical hazards may require other forms of protection----see supervisor or EH&S.
No stickers or other material that could cover a defect in the helmet is permitted.
Type of Hazard: Eye/Face
Sources: Chemicals, Dusts, Heat, Impact, Light Radiation
Required Protection: Eye protection shall be appropriate for the hazards present and shall meet the requirements of ANSI Z87.1-1989 as indicated by a stamp on the lens and frame. Eye protection must have side shields if there is a risk from flying objects. Affected employees who wear prescription lenses shall wear eye protection that incorporates the prescription in its design, or shall wear eye protection that fits over the prescription lenses.
The following chart taken from 29 CFR 1910 Subpart I Appendix-B provides general guidance for the proper selection of eye and face protection to protect against hazards associated with the listed hazard "source" operations.

Notes to Eye and Face Protection Selection Chart:
(1) Care should be taken to recognize the possibility of multiple
and simultaneous exposure to a variety of hazards. Adequate
protection against the highest level of each of the hazards should be
provided. Protective devices do not provide unlimited protection.
(2) Operations involving heat may also involve light radiation. As
required by the standard, protection from both hazards must be
(3) Faceshields should only be worn over primary eye protection
(spectacles or goggles).
(4) As required by the standard, filter lenses must meet the
requirements for shade designations in 1910.133(a)(5). Tinted and
shaded lenses are not filter lenses unless they are marked or
identified as such.
(5) As required by the standard, persons whose vision requires the
use of prescription (Rx) lenses must wear either protective devices
fitted with prescription (Rx) lenses or protective devices designed
to be worn over regular prescription (Rx) eyewear.
(6) Wearers of contact lenses must also wear appropriate eye and
face protection devices in a hazardous environment. It should be
recognized that dusty and/or chemical environments may represent an
additional hazard to contact lens wearers.
(7) Caution should be exercised in the use of metal frame
protective devices in electrical hazard areas.
(8) Atmospheric conditions and the restricted ventilation of the
protector can cause lenses to fog. Frequent cleansing may be
(9) Welding helmets or faceshields should be used only over primary
eye protection (spectacles or goggles).
(10) Non-sideshield spectacles are available for frontal protection
only, but are not acceptable eye protection for the sources and
operations listed for "impact."
(11) Ventilation should be adequate, but well protected from splash
entry. Eye and face protection should be designed and used so that it
provides both adequate ventilation and protects the wearer from
(12) Protection from light radiation is directly related to filter
lens density. See note (4). Select the darkest shade that allows
Each affected employee will use equipment with filter lenses that have a shade number appropriate for the work being performed for protection from injurious light radiation. The following chart taken from 29 CFR 1910.133 is a listing of appropriate shade numbers for various operations.

Footnote(*) As a rule of thumb, start with a shade that is too dark
to see the weld zone. Then go to a lighter shade, which gives
sufficient view of the weld zone without going below the minimum. In
oxyfuel gas welding or cutting where the torch produces a high yellow
light, it is desirable to use a filter lens that absorbs the yellow
or sodium line in the visible light of the (spectrum) operation.
Footnote(**) These values apply where the actual arc is clearly
seen. Experience has shown that lighter filters may be used when the
arc is hidden by the workpiece.
Type of Hazard: Foot/Leg/Torso
Sources: Falling/Rolling objects, penetration, sharp objects, heat/sparks, electrical and chemical hazards, severe cuts and abrasions.
Required Protection: Protective footwear which meets the requirements of ANSI Z41-1991 provides both impact and compression protection. Where necessary, safety shoes can be obtained which provide puncture protection. Certain situations may require metatarsal (for roll-over), electrical, or chemical protection. Supervisors will work with Environmental Health & Safety Office to determine adequate protection if such hazards arise. Leg protection may need to be in the form of leggings or aprons made of leather or other suitable material when performing welding, high heat operations, severe puncture risk operations, or when there is a quantity exposure to corrosive/toxic chemicals. For a less risky exposure to the above hazards (such as what is commonly encountered in maintenance and chemical lab operations) pants that leave no skin exposed and are made of a durable cloth are required. Torso protection may require vests, jackets, aprons, coveralls, or full body suits. These also must be made of an appropriate material for the task. Refer to the manufacturers guidelines against specific hazards.
Type of Hazard: Hand/Arm
Sources: Severe cuts and abrasions, chemical exposure, punctures, temperature extremes and electrical hazards.
Required Protection: No type of glove provides protection from all hand hazards, and chemical resistant gloves have a limited time before a chemical penetrates. Thus, there may be times when different types of gloves need to be combined or changed frequently. A specific list of the chemical resistivity of different types of gloves is available in the Physical Plant Stockroom, Chemical Stockroom, and the Environmental Health and Safety Office and should be consulted if a suitable type is in question. Also, the type of glove needed should be listed on the products Material Safety Data Sheet. Sleeves for protection against various hazards also need to be considered, with material that provides adequate protection for the task.
Maintenance: All personal protective equipment needs to be properly maintained. Cleaning is particularly important for eye and face protection where dirty or fogged lenses could impair vision. All PPE needs to be maintained at regular intervals and disposed of if decontamination is not possible or its effectiveness is reduced.
Training: Laboratory personnel exposed to chemical hazards are unique in that they determine on a daily basis what chemicals they will work with, how they will work with the hazard and for what duration. Subsequently, they will also determine when and what type of PPE is necessary, the proper way to wear the equipment, and its maintenance and limitations. All other employees will have documented training performed by their supervisors and/or the Environmental Health & Safety Office.
