8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Sodium hydroxide: Peak limitation = 2 mg/m³
Peak Limitation: A ceiling concentration which should not be
exceeded over a measurement period which should be as
short as possible but not exceeding 15 minutes.
Engineering Controls: Ensure ventilation is adequate to maintain
air concentrations below Exposure Standards. Avoid
generating and breathing in dusts. Use with local exhaust
ventilation or while wearing dust mask, Keep containers
closed when not in use.
Personal Protective Equipment:
Clothing – Overalls
Gloves – Impervious natural rubber, butyl rubber,
nitrile or PVC gloves should be worn.
Note: Resistance of glove materials can vary. Evaluate
resistance under conditions of use and maintain PPE
carefully.
Footwear – Safety shoes
Eye-protection – Chemical goggles
Other – Dust mask
Wear overalls, chemical goggles and impervious gloves. Avoid
generating and inhaling dusts. If dust exists, wear dust
mask/respirator meeting the requirement of AS/NZS 1715 and
AS/NZS 1716. Always wash hands before smoking, eating,
drinking or using the toilet. Wash contaminated clothing and
other protective equipment before storage or re-use.
These Exposure Standards are guides to be used in the control
of occupational health hazards. All atmospheric contamination
should be kept to as low a level as is workable. These exposure
standards should not be used as fine dividing lines between
safe and dangerous concentrations of chemicals. They are not a
measure of relative toxicity.
