Welding Shields
Welding shields are similar in design to face shields but offer additional protection from infrared
or radiant light burns, flying sparks, metal splatter, and slag chips encountered during welding,
brazing, soldering, resistance welding, bare or shielded electric arc welding, and oxyacetylene
welding and cutting operations.
It is recommended that equipment fitted with appropriate filter lenses always be used to protect
against light radiation. Tinted and shaded lenses are not filter lenses unless they are marked or
identified as such.
LASER Eye Protection
A single pair of safety glasses is not available for protection from all LASER outputs. The type
of eye protection required is dependent on the spectral frequency or specific wavelength of the
LASER source. If you have questions on the type of eyewear that should be worn with your
specific LASER, contact your EHSO. See the LASER Hazards section for more information.
11.5 Hand Protection
Most accidents involving hands and arms can be classified under four main hazard categories:
chemicals, abrasions, cuts, and heat/cold. Gloves must be worn whenever significant potential
hazards from chemicals, cuts, lacerations, abrasions, punctures, burns, biologicals, or harmful
temperature extremes are present. The proper use of hand protection can help protect from
potential chemical and physical hazards. Gloves must be worn when using chemicals that are
easily absorbed through the skin and/or particularly hazardous substances (such as “select
carcinogens,” reproductive toxins, and substances with a high degree of acute toxicity).
***There is no one type of glove that offers the best protection against all chemicals or one
glove that totally resists degradation and permeation to all chemicals. All gloves must be
replaced periodically, depending on the type and concentration of the chemical, performance
characteristics of the gloves, conditions and duration of use, hazards present, and the length of
time a chemical has been in contact with the glove.
All glove materials are eventually permeated by chemicals; however, they can be used safely for
limited time periods if specific use and other characteristics (e.g., thickness, permeation rate, and
time) are known. The EHSO can provide assistance with determining the resistance to chemicals
of common glove materials and determining the specific type of glove material that should be
worn for use with a particular chemical.
11.5.1 Selecting the Proper Gloves
Before working with any chemical, always read manufacturer instructions and warnings on
chemical container labels and MSDSs. Recommended glove types are sometimes listed in the
PPE section of the MSDS. If the recommended glove type is not listed on the MSDS, then
laboratory personnel should consult with the manufacturers’ glove selection charts. These charts
typically include commonly used chemicals that have been tested for the manufacturers’
