FIRST AID MEASURES

 

NO DECONTAMINANTS OTHER THAN WATER SHOULD BE USED ON HUMANS

Contact with skin:

  • Immediately flush/wash affected area with plenty of water while removing all contaminated clothing and shoes for at least 30 minutes.
  • Seek immediate medical attention.
  • Contaminated clothing and footwear should be discarded.

Contact with eyes:

  • Immediately flush/wash out with plenty of water for at least 30 minutes.
  • Seek medical attention.

Inhalation:

  • Remove patient to fresh air.
  • Keep them quiet and warm
  • Apply artificial respiration only if patient is not breathing.
  • Avoid mouth to mouth resuscitation. Use alternate methods: bottled air, bottled oxygen or a compressed air driven apparatus.
  • Pursue immediate medical attenntion.

Ingestion:

  • Do not induce vomiting.
  • Rinse mouth with water (DO NOT SWALLOW rinse water).
  • Never give anything by mouth to an unconscious person.
  • Obtain immediate medical attention.

General:

  • NOTE TO PHYSICIANS:
  • Rescuers should take suitable precautions to avoid becoming casualties themselves.
  • Corrosive to tissue.
  • No specific antidote, treat symptomatically and supportively.

FIRE-FIGHTING MEASURES

  • Not flammable but can cause oxidizable materials to catch fire.
  • Use extinguishable media appropriate to surrounding conditions.
  • Use waterspray to keep containers cool, knock down combustion vapours and extinguish fire.
  • Do not use water jet.
  • Portable containers should be moved if possible and without risk.
  • Wear gas tight Chemical Protection Suit and Positive-Pressure Breathing Apparatus.

ACCIDENTAL RELEASE MEASURES

 

Personal precautions:

  • Evacuate the area and keep personnel upwind.
  • Full protective clothing, including self-contained breathing apparatus, must be used. - see Section 8.

Environmental precautions:

  • Dike for recovery or absorb liquid with sand, earth or other non-reactive material.
  • Covering the surface of spilled bromine with plastic sheeting or chemical foam can minimise vapour release.
  • Neutralise liquid bromine with slaked lime, lime water slurry or soda ash.
  • Knock down vapour cloud with water spray (not jets), however, note that excessive use of water can complicate spill situations.

Methods for cleaning up:

  • Consult an expert.
  • Do not allow to enter public sewers and watercourses.
  • Where possible, contain spill control run-off.

HANDLING AND STORAGE

 

Handling:

  • Avoid breathing vapours and any other bodily contact.
  • Keep above minus 6.7°C to prevent freezing.
  • All personnel handling bromine should be fully trained and provided with suitable protective clothing. Enclosed systems should be used for processes involving bromine.
  • Pipework and tanks should be checked regularly for leaks.
  • In laboratories, bromine containers should be kept closed and only handled in fume cupboards or under extraction hoods.
  • Warm containers should be allowed to cool to room temperature before they are opened.
  • Before transferring bromine between containers, a check should be made that the receiving container has room for it.

Storage: 

  • Store in a dry, well-ventilated area away from incompatible materials (see ‘materials to avoid'). Containers should be stored upright and all be clearly labelled.
  • Glass, ceramic nickel or lead containers are suitable for bromine. Lead-lined steel tanks can be used. Only highly fluorinated plastics will resist corrosion. A free space of 8-10% by volume should be left in the container.

PERSONAL PROTECTION

Exposure limit values:

OES/LTEL : 0.1ppm ( 0.66mg/m3)

OES/STEL: 0.2ppm (1.32mg/m3)

Applicable for all individual EU countries in 2007.

Respiratory protection: 

In poorly ventilated areas or confined spaces, use an airline respirator of self-contained breathing apparatus.

Hand protection:

  • Selection of a suitable glove depends on work conditions and whether the product is present on its own or in combination with other substances.
  • It has been found that gloves made from nitrile rubber or neoprene provide short-term splash protection.
  • Breakthrough time is dependent on the characteristics of the brand of glove used, consult your supplier.
  • Gloves should be replaced immediately if signs of degradation are observed.

Eye protection:

Chemical safety goggles or face shield with safety glasses.

Skin protection:

Wear suitable protective clothing and eye/face protection.

Environmental exposure controls:  

To prevent spillages entering the aquatic and soil compartments of the environment bromine storage should be placed inside a fully bunded area of sufficient size to contain the volume plus 10%.

Maintenance of a shallow layer of water in the bund or the provision of a trench system capable of quickly introducing such a layer is advisable to minimise release of vapour to the atmosphere. The use of bromine resistant anti-freeze agent may be necessary to prevent freezing at low ambient temperatures. Bromine installations should always be vented via an absorption/scrubbing system* to prevent fugitive emissions to the atmosphere.

 

*A suitable absorbent is 5-15% w/w sodium hydroxide solution.

STABILITY AND REACTIVITY

Conditions to avoid: Extreme temperatures.

Materials to avoid:

  • Contact with combustible materials may cause fire.
  • Bromine is a very reactive substance, for example in the presence of water reacts vigorously with phenols, amines, hydrocarbons, organic acids and aromatic and aliphatic ketones.
  • Dry bromine reacts violently with many metals, notably aluminium, titanium, mercury and potassium and with phosphorus.

Hazardous composition products:

  • Stable under normal conditions.
  • Hazardous polymerisation will not occur.

DISPOSAL CONSIDERATION

 

  • Disposal can be a hazardous operation; seek specialist advice.
  • Dilute and neutralise before transferring to an approved disposal facility.
  • Disposal should be in accordance with local, state or national legislation.
