equipment for fire-fighters
6. Accidental release measures
Personal precautions : No action shall be taken involving any personal risk or without suitable training.
Evacuate surrounding areas. Keep unnecessary and unprotected personnel from
entering. Do not touch or walk through spilled material. Provide adequate ventilation.
Wear appropriate respirator when ventilation is inadequate. Put on appropriate personal
protective equipment (see section 8).
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers. Inform the relevant authorities if the product has caused environmental
pollution (sewers, waterways, soil or air).
Large spill : Move containers from spill area. Approach release from upwind. Prevent entry into
sewers, water courses, basements or confined areas. Vacuum or sweep up material
and place in a designated, labeled waste container. Dispose of via a licensed waste
disposal contractor. Note: see section 1 for emergency contact information and section
13 for waste disposal.
Small spill : Move containers from spill area. Vacuum or sweep up material and place in a
designated, labeled waste container. Dispose of via a licensed waste disposal
contractor.
7. Handling and storage
Handling : Put on appropriate personal protective equipment (see section 8). Eating, drinking and
smoking should be prohibited in areas where this material is handled, stored and
processed. Workers should wash hands and face before eating, drinking and smoking.
Persons with a history of skin sensitization problems or asthma, allergies or chronic or
recurrent respiratory disease should not be employed in any process in which this
product is used. Do not get in eyes or on skin or clothing. Do not ingest. Use only with
adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Keep
in the original container or an approved alternative made from a compatible material,
kept tightly closed when not in use. Empty containers retain product residue and can be
hazardous. Do not reuse container.
Storage : Store in accordance with local regulations. Store in original container protected from
direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials
(see section 10) and food and drink. Keep container tightly closed and sealed until ready
for use. Containers that have been opened must be carefully resealed and kept upright
to prevent leakage. Do not store in unlabeled containers. Use appropriate containment
to avoid environmental contamination.

Engineering measures : Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or
other engineering controls to keep worker exposure to airborne contaminants below any
recommended or statutory limits.
Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before
eating, smoking and using the lavatory and at the end of the working period. Appropriate
techniques should be used to remove potentially contaminated clothing. Wash
contaminated clothing before reusing. Ensure that eyewash stations and safety showers
are close to the workstation location.
Personal protection
Respiratory : Use a properly fitted, air-purifying or air-fed respirator complying with an approved
standard if a risk assessment indicates this is necessary. Respirator selection must be
based on known or anticipated exposure levels, the hazards of the product and the safe
working limits of the selected respirator.
Hands : Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary.
Eyes : Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists or
dusts.
Skin : Personal protective equipment for the body should be selected based on the task being
performed and the risks involved and should be approved by a specialist before handling
this product.
