GALLIUM

Gallium is a silvery-white liquid at room temperature. Ingestion of this material may be toxic. It is corrosive to aluminum. If exposed to high temperatures, gallium may emit toxic fumes which may form a corrosive alkaline solution with water. It is soluble in most acids and alkalis. It is used as a semiconductor material.

• Strong Reducing Agent

Stable in dry air, in moist air it tarnishes

Excerpt from 172 [Gallium and Mercury]:

Non-combustible, substance itself does not burn but may react upon heating to produce corrosive and/or toxic fumes. Runoff may pollute waterways. (ERG, 2020)

Excerpt from 172 [Gallium and Mercury]:

Inhalation of vapors or contact with substance will result in contamination and potential harmful effects. Fire will produce irritating, corrosive and/or toxic gases. (ERG, 2020)

Metals, such as GALLIUM, are reducing agents and tend to react with oxidizing agents (i.e. hydrogen peroxide). Their reactivity is strongly influenced by their state of subdivision: in bulk they often resist chemical combination; in powdered form they may react more rapidly. Reacts violently with chlorine and other halogens at ambient temperatures [Bretherick, 5th Ed., 1995].

Excerpt from 172 [Gallium and Mercury]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet).

FIRE: When any large container is involved in a fire, consider initial evacuation for 500 meters (1/3 mile) in all directions. (ERG, 2020)

Excerpt from 172 [Gallium and Mercury]:

Use extinguishing agent suitable for type of surrounding fire. Do not direct water at the heated metal. (ERG, 2020)

Excerpt from 172 [Gallium and Mercury]:

Do not touch or walk through spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Do not use steel or aluminum tools or equipment. Cover with earth, sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. For mercury, use a mercury spill kit. Mercury spill areas may be subsequently treated with calcium sulphide/calcium sulfide or with sodium thiosulphate/sodium thiosulfate wash to neutralize any residual mercury. (ERG, 2020)

Excerpt from ERG Guide 172 [Gallium and Mercury]:

Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

Excerpt from 172 [Gallium and Mercury]:

Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air if it can be done safely. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim calm and warm.
