Exposure controls
Protective equipment
Appropriate engineering
controls
Provide adequate ventilation. Personal, workplace environment or biological monitoring may
be required to determine the effectiveness of the ventilation or other control measures and/or
the necessity to use respiratory protective equipment. Use process enclosures, local exhaust
ventilation or other engineering controls as the primary means to minimize worker exposure.
Personal protective equipment should only be used if worker exposure cannot be controlled
adequately by the engineering control measures. Ensure control measures are regularly
inspected and maintained. Ensure operatives are trained to minimize exposure.
Eye/face protection Eyewear complying with an approved standard should be worn if a risk assessment indicates
eye contact is possible. Personal protective equipment for eye and face protection should
comply with OSHA 1910.133. Wear tight-fitting, chemical splash goggles or face shield. If
inhalation hazards exist, a full-face respirator may be required instead.
Hand protection Chemical-resistant, impervious gloves complying with an approved standard should be worn if
a risk assessment indicates skin contact is possible. The most suitable glove should be
chosen in consultation with the glove supplier/manufacturer, who can provide information
about the breakthrough time of the glove material. To protect hands from chemicals, gloves
should comply with OSHA 1910.138 and be demonstrated to be impervious to the chemical
and resist degradation. Considering the data specified by the glove manufacturer, check
during use that the gloves are retaining their protective properties and change them as soon
as any deterioration is detected. Frequent changes are recommended.
Other skin and body
protection
Appropriate footwear and additional protective clothing complying with an approved standard
should be worn if a risk assessment indicates skin contamination is possible.
