Emergency Response Information
HIGHLY CORROSIVE TOXIC SUBSTANCE

1. Characteristics
  • Toxic by ingestion, inhalation or skin absorption.
  • Flashpoint below 60°C.
  • Highly corrosive, causing severe damage to skin, eyes and air passages.
  • Miscible with water (more than 10%), OR heavier than water.

2. Hazards
  • Heating of container(s) will cause pressure rise with risk of bursting and subsequent explosion.
  • Gives off toxic and corrosive fumes, also when burning.
  • May form explosive mixture with air.
  • 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

4. Intervention Actions
  4.1 General
  • No smoking, eliminate ignition sources.
  • Keep upwind. Put on protective equipment before entering danger area.

  4.2 Spillage
  • Stop leaks if possible.
  • Contain spillage by any means available.
  • Use low sparking hand tools and intrinsically safe equipment.
  • If substance is a liquid, check explosive limits.
  • Absorb substance in sand or earth or any other suitable material, or cover with alcohol resistant foam.
  • If substance has entered a water course or sewer, inform the responsible authority.
  • Ventilate sewers and basements where there is no risk to personnel or public.

  4.3 Fire (involving the substance)
  • Keep container(s) cool with water.
  • Extinguish with water fog (spray).
  • Do not use water jet to extinguish.
  • Use water spray to knock down fire fumes if possible.
  • Avoid unnecessary run-off of extinguishing media which may cause pollution.

5. First Aid
  • If substance has got into eyes, wash out with water for at least 15 minutes and seek immediate medical attention.
  • Remove contaminated clothing immediately and drench affected skin with plenty of water.
  • Persons who have been in contact with the substance or have inhaled fumes should get immediate medical attention. Pass on all available product information.
  • In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing adhering to skin.
  • Mouth to mouth resuscitation should be avoided. Use alternative methods, preferably with oxygen or compressed air driven apparatus.

6. Essential Precautions For Product Recovery
  • Ensure proper earthing of pumping equipment.
  • Use flame proof pump(s). If electrically driven, minimum class T3.
  • Use acid resistant equipment.
  • Recover spilled product in hermetically sealed container.

7. Precautions After Intervention
  7.1 Undressing
  • Drench contaminated suit and breathing apparatus with water before removing facemask and suit.
  • Use chemical protection suit and self contained breathing apparatus while undressing contaminated co-workers or handling contaminated equipment.
  • Contain decontamination run off.

  7.2 Equipment Clean Up
  • Drench with water and seek specialist advice before transporting from incident.
