• Keep containers cool and protect exposed material.
• If a leak or spill has not ignited, water spray may be used to flush spills away from exposures.

Hazards from combustion products:

• Not combustible. However, can liberate highly flammable hydrogen gas when in contact with certain metals.

Precautions for fire fighters and special protective equipment:

• Alert fire brigade and tell them location and nature of hazard.
• Wear breathing apparatus plus protective gloves.
• Prevent, by any means available, spillage from entering drains or water courses.
• Use fire fighting procedure suitable for surrounding area.
• Use water delivered as a fine spray to control the fire and cool adjacent area.
• Fire fighters to wear self-contained breathing apparatus if risk of exposure to vapour or products of combustion as well as structural fire fighter uniform.

Emergency precautions:

• Personnel involved in the clean up should wear full protective clothing.
• Evacuate all unnecessary personnel.
• Increase ventilation.
• Avoid walking through spilled product as it may slippery.
• Stop leak if safe to do so.
• Do not let product reach drain or waterways; advise the Environmental Protection Authority or your local Waste Management.
• Use clean, non-sparking tools and equipment.

Methods and materials for containment and clean up:

• Soak up spilled product using absorbent, non-combustible material such as sand or soil.
• Avoid using sawdust or cellulose.
• When saturated, collect material into suitable, labelled, dry, sealable containers and hold for safe disposal.
• Once pick-up is complete, flush spill site with plenty of water to eliminate any residue.
• Hold contaminated water for treatment/disposal.

Handling:

• Wash thoroughly after handling.
• Use only in a well ventilated area.
• Avoid contact with eyes, skin and clothing.
• Empty containers retain product and residue (liquid or vapour), and can be dangerous.
• Keep container tightly closed.
• Always wash hands before smoking, eating or using the toilet.
• Wash contaminated clothing and other protective equipment before storage or re-use.
• Do not dispose of material to sewers or waterways.
• When diluting acid, always add slowly to water in small amounts and never use hot water. Adding water to acid solution can cause uncontrolled boiling and splashing.

Storage:

• Store in a tightly closed container.
• Keep from contact with oxidizing agents.
• Store in cool, dry, well-ventilated area away from incompatible substances.
• Keep containers closed at all times, check regularly for leak.

Exposure standards:

For hydrochloric acid: TWA = 5 ppm Peak limitation (7.5 mg/mu00b3 Peak limitation)

Biological limit values: None established

Engineering controls:

• The use of local exhaust ventilation is recommended to control process emissions near the source and keep employee exposures as low as possible.
• Laboratory samples should be handled in a fume hood.
• Provide mechanical ventilation of confined spaces.
• Use explosion proof ventilation equipment.

Personal protective equipment:

• Respiratory protection: Where concentration in air may exceed the limits described in the National Exposure Standards, it is recommended to use a half face filter mask to protect from overexposure by inhalation with an acid gas filter according to NZS1715/1716.
