Exposure controls / personal protection

Exposure limit values
Occupational exposure limit value (sulphur dioxide - 7446-09-5):
- AGW (Germany): 0.5 ppm; 1.3 mg/m³ (long term).
- AGW (Germany): 0.5 ppm (STV 15 minutes average value; a momentary value of 1 mL/m³ (2.7 mg/m³) should not be exceeded); 1.3 mg/m³ (short term).
- Belgium and Spain: 2 ppm; 5.3 mg/m³ (long term).
- Belgium and Spain: 5 ppm; 13 mg/m³ (short term).
- France: 2 ppm; 5 mg/m³ (long term).
- France: 5 ppm; 10 mg/m³ (short term).
- Netherlands: 0.7 mg/m³ (short term).
- United States: 5 ppm; 13 mg/m³ (long term).

Personal protection equipment:
- Respiratory protection required in case of: Handling larger quantities exceeding critical value.
- Suitable respiratory protective equipment: Combination filtering device (DIN EN 141).
- Type of mask: Half-face mask (DIN EN 140).
- Filtering device: E-P2 or E-P3

Hand protection:
- Use protective gloves.
- The glove material must be sufficiently impermeable and resistant to the substance.
- Check the tightness before wear.
- Gloves should be well cleaned before being removed, then stored in a well ventilated location.
- Pay attention to skin care.
- Textile or leather gloves are completely unsuitable.
- Suitable materials for gloves are (brakthrough time>=8 hours): NR (Natural rubber (Caoutchouc), Natural latex) - NR (0,5 mm); CR (polychloroprenes, Chloroprene rubber) - CR (0,5 mm); NBR (Nitrile rubber)- NBR (0,35 mm); Butyl rubber - Butyl (0,5 mm); FKM (fluororubber) - FKM (0,4 mm); PVC (Polyvinyl chloride)- PVC (0,5 mm).
The times listed are suggested by measurements taken at 22°C and constant contact. Temperatures raised by warmed substances, body heat, etc. and a
weakening of the effective layer thickness caused by expansion can lead to a significantly shorter breakthrough time. In case of doubt contact the gloves'
manufacturer. A 1.5-times increase / decrease in the layer thickness doubles / halves the breakthrough time. This data only applies to the pure substance. Transferred to mixtures of substances, these figures should only be taken as an aid to orientation.

Eye protection:
- Suitable eye protection: Tightly sealed safety glasses.

Protective clothing:
- Suitable protection of the body: Chemical resistant safety shoes. Protective clothing: DIN EN 13034

General health and safety measures:
- When using do not eat, drink, smoke, sneeze.
- Wash hands and face before breaks and after work and take a shower if necessary.
- Draw up skin protection programme.
- Used working clothes must not be worn outside the working area.
- Separate storage of work clothes. Immediately remove any contaminated clothing, shoes or stockings.
- In the immediate working surroundings there must be: Emergency shower installed. Make available sufficient washing facilities. Provide eye shower and label its location conspicuously.
- Set out skin protection guidelines.
- Only wear fitting, comfortable and clean protective clothing.
