Clothes and shoes!
Everyone MUST complete this section.
Covering on various parts of your skin is necessary depending on
the stipulations of the chemical hygiene plan, your hazard assessment and standard operating procedures. For
general chemical and biological work, skin covering to wrists is generally
required, depending on the quantities and hazards of the material(s). For work with
ultraviolet light sources (some lasers, some
welding operations, some biological work) it is common for certain skin covering to be
stipulated in the hazard assessment or SOP. Fire-resistant material is recommended
for clothes worn for work around class 4 lasers or when welding.
Arc-Flash rated clothing is required for work on some energized electrical equipment.
The 2014 Chemical Hygiene Plan requires a minimum of covering to the ankles, wrists and throat, and closed
toe shoes. In addition, a minimum PPE requirement is safety glasses or goggles, a lab coat, and chemical
resistant gloves.
These must be worn at all times while in the lab unless you are working at a desk in the
lab that is separated from chemical operations.
These requirements do not apply to labs that involve solely mechanical, computer, laser or other non-ionizing radiation,
or electrical operations.
Except for
special equipment that would not constitute part of an individual's normal wear, e.g.,
boots with reinforced toes, the items referred to here as "other cover" are
regarded as personal, and they are to be provided by the employee. The extent of
coverage (to wrists, to throat, to ankles) should conform with those stated in
the chemical hygiene plan, the hazard assessment and the SOP. Nylon stockings do not qualify as protective
covering to ankles, nor do sheer tights. Clothes must not have holes, rips, or
snags which might catch on equipment or furniture, or which might catch fire more easily
than intact clothing. Certain operations (some welding, large quantities of
cryogens) require cuffless trousers; check the hazard assessment.
Note that if your clothing does not meet the requirements of the hazard assessment, the use of additional
PPE, such as a lab coat, can be used to meet the requirement.
If the hazard assessment stipulates covering to throat, this means the shirt or blouse should come to the throat (above or at the
clavicles = collarbones); if the shirt has buttons they should be buttoned to this point, at
least. If the hazard assessment or SOP specifies covering to wrists, the wrists
should be covered, and any cuff buttons should be buttoned. Shoes should cover
the feet front, back, and top, and should be quickly removable. If the shoes have
laces they should be of such a design that spilled liquids will not penetrate easily or
quickly. For some welding operations it is
important that the worker's shirt be worn outside of the trousers (i.e. not
tucked into the trousers). The hazard assessment or SOP should specify the exact clothing requirements.
Your
"street clothes" (your "normal," "daily wear," "other
cover") is only appropriate and sufficient if it is what's required by the hazard
assessment(s) which apply to the work in which you're engaged. Furthermore, your
employer does not replace ruined clothes or shoes that could have been protected by the
use of further outer-wear such as lab coat, apron, or in extreme cases, coveralls or a
chemically resistant suit.

that has been contaminated with hazardous materials should be taken home for
cleaning. This includes your clothes and shoes. If / when they become
