Effects of Short Term Exposure: The substance is substance corrosive to the eyes, skin and respiratory tract. Inhalation may cause lung oedema. The substance hydrolyses rapidly on exposure to moisture releasing H2S.

Chemical Dangers: The solution in water is a strong base. It reacts violently with acid and is corrosive. Decomposes on heating. This produces sulfur oxides. Decomposes on contact with water. This produces highly toxic and flammable hydrogen sulfide. Attacks metal. Reacts with strong oxidants. This produces sulfur oxides.

Fire Potential: Flammable when exposed to heat or flame. Spontaneous combustion.

Fire Hazard: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Skin, Eye and Respiratory Irritations: A corrosive irritant to skin, eyes, and mucous membranes.

Isolation and Evacuation

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Firefighting

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

SMALL FIRE: Dry chemical, CO2 or water spray.

LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

Non-Fire Response

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). 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. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2016)

Protective Clothing

Rubber protective equipment, such as apron, boots, splash- proof goggles, gloves; canister-type respirator or self-contained breathing apparatus. (USCG, 1999)

First Aid

INHALATION: move victim from contaminated atmosphere; call physician; if breathing has ceased, start mouth-to-mouth resuscitation.

EYES: immediately flush with large quantities of running water for a minimum of 15 min.; obtain medical attention as soon as possible; while awaiting instructions from physician, patient may be kept in a dark room and ice compresses applied to the eyes and forehead.

SKIN: immediately flush affected areas with water; obtain medical attention if irritation persists.

INGESTION: obtain medical attention as soon as possible; if patient is conscious, induce vomiting by giving large amounts of water or warm salty water (2 tablespoons of table salt to a pint of water); if this measure is unsuccessful, vomiting may be induced by tickling back of patient's throat with a finger. Vomiting should be encouraged until the vomitus is clear. If patient is unconscious, do not give anything but ensure there is no obstruction to breathing (his tongue should be kept forward and false teeth removed). He will be less likely to aspirate vomitus if he is placed in a face-down position.

Hazardous Reactivities & Incompatibilities: Reacts violently with diazonium salts. Spontaneous combustion.

Hazard Statements:

Self-heating; may catch fire [Danger Self-heating substances and mixtures]

May be corrosive to metals [Warning Corrosive to Metals]

Toxic if swallowed [Danger Acute toxicity, oral]

Causes severe skin burns and eye damage [Danger Skin corrosion/irritation]

Causes serious eye damage [Danger Serious eye damage/eye irritation]

Very toxic to aquatic life [Warning Hazardous to the aquatic environment, acute hazard]

Safe Storage: Fireproof. Dry. Keep in a well-ventilated room. Separated from acids and strong oxidants.
