Exposure controls/personal protection
Specific control parameter
Arsenic compounds as As:
PEL: 0.1 mg/m3, Max. workplace conc. (NPK-P): 0.4 mg/m3
Personal protective equipment:
Respiratory protection:
required when vapours/aerosols are generated.
Eye protection:
required
Hand protection:
required
Protective clothing should be selected specifically for the working place,
depending on concentration and quantity of the hazardous substances handled.
The resistance of the protective clothing to chemicals should be ascertained with
the respective supplier.
Other protective equipment:
Suitable protective clothing.
Industrial hygiene:
Immediately change contaminated clothing. Apply skin-protective barrier cream.
Wash hands and face after working with substance. Under no circumstances eat or
drink at workplace.
Wear appropriate respirator, chemical-resistant gloves, safety goggles, other protective clothing. Safety shower
and eye batch. Use only in a chemical fume hood. Do not breathe dust. Do not get in eyes, on skin, on clothing.
Avoid prolonged or repeated exposure. Wash thoroughly after handling. Discard contaminated clothing and
shoes. Irritant. Keep tightly closed. Store in a cool dry place.
