8.2. 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 minimise 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 minimise exposure. The

engineering controls also need to keep gas, vapour or dust concentrations below any lower

explosive limits. Use explosion-proof ventilating equipment.

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 European Standard EN166. Unless the assessment indicates a higher degree of

protection is required, the following protection should be worn: Tight-fitting safety glasses.

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 European Standard EN374. 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.
