CORROSIVE SUBSTANCE
1. Characteristics
- Corrosive, causing damage to skin, eyes and air passages.
- Violent reaction with water, subdued by copious application.
- Flash point above 60°C OR not flammable.
2. Hazards
- Heating of container(s) will cause pressure rise with risk of bursting and subsequent explosion.
- Gives off corrosive and irritant fumes, also when burning.
- May attack metals and produce hydrogen gas which may form explosive mixture with air.
- The vapour may be invisible and is heavier than air. It spreads along the ground and may enter sewers and basements.
3. Personal Protection
- Chemical protection suit.
- Self contained breathing apparatus.
- Gas tight suit in close proximity to substance or vapour.
4. Intervention Actions
4.1 General
- Keep upwind. Put on protective equipment before entering danger area.
- Minimise number of personnel in risk area.
4.2 Spillage
- Stop leaks if possible.
- Dilute spillage with water spray as far as necessary to reduce hazard. Contain run off by any means available.
- If substance has entered a water course or sewer, inform the responsible authority.

6. Essential Precautions For Product Recovery
- Use acid resistant equipment.
- Recover spilled product in vented container fitted with absorption filter.
7. Precautions After Intervention
7.1 Undressing
