3.   Hazards Identification


Routes of Entry: (under normal conditions of use)


Skin Contact: Moderate Eye Contact: Major        Ingestion: Moderate       Inhalation: Major


Effects of Short-Term (Acute) Exposure:

Inhalation: Selenium is a severe irritant with immediate or delayed effects: cough, difficult breathing, chills, garlic breath, fever, headache, chemical pneumonia, and bronchial spasms. Nitric acid vapors are corrosive to the nose, throat, and mucous membranes. Prolonged exposure may result in severe irritation and tissue damage.

Skin Contact: Contact with liquid can cause severe irritation, burns. Vapor or mist may cause redness, irritation and burns if contact is prolonged. May lead to dermititis or sensitization.

Eye Contact: Low concentrations of vapor or mist (10 - 35 ppm) can be immediately irritating and result in redness. Concentrated vapor, mist or splashed liquid can cause severe irritation, burns and permanent blindness.

Hazards Identification, continued


Ingestion: Liquid can cause severe corrosive burns to mouth, throat, esophagus and stomach. Symptoms may include difficulty in swallowing, intense thirst, nausea, vomiting, diarrhea, kidney

damage, gastrointestinal disorders, and in severe cases, collapse and death. Small amounts of acid which enter the lungs during ingestion or vomiting (aspiration) can cause serious lung injury and death.


Effects of Long-Term (Chronic) Exposure:

Repeated and prolonged exposure to low concentrations of mist or vapor can cause discolouration and damage to tooth enamel, bleeding of the nose and gums, gastrointestinal symptoms, and chronic bronchitis and gastritis. Repeated exposure to low concentrations of liquid, mist or vapour can cause redness, swelling, sensitization, and pain (dermatitis). Metallic taste and garlic breath are signs of selenium absorption. No evidence of carcinogenicity in human studies. This product does not accumulate in the body.

Medical Conditions Aggravated By Exposure:

Pre-existing respiratory and skin disorders.



4.   First Aid Measures


Eye Contact: Flush contaminated eye(s) with lukewarm, gently running water for 30 minutes, holding eyelids open. Seek medical attention if irritation persists.


Skin Contact: Wash affected area immediately with mild soap and water and continue for 15 minutes. If irritation persists, seek immediate medical attention. Remove any contaminated clothing and launder clothing before reuse.


Inhalation: If victim has been exposed to vapors remove to fresh air. If breathing has stopped, a trained person should perform artificial respiration. Get medical attention immediately.


Ingestion: If small amounts have been ingested, do not induce vomiting. Dilute contents of stomach with 1-2 glasses of water. If large amounts have been ingested, see a doctor immediately for gastric lavage with a cuffed endotracheal tube. If vomiting occurs naturally have victim lean forward to reduce risk of aspiration. Seek immediate medical attention.



5.   Fire Fighting Measures



Flash point:                                          Not Applicable

Autoignition temperature:                    Not applicable. See information under “Fire Fighting Instructions”

Lower Explosive Limit:                        Not established

Upper Explosion Limit:                        Not established

Sensitivity to Impact:                           Not sensitive.

Sensitivity to Static Discharge: Not sensitive.


Hazardous Combustion Products: Nitrogen oxides, toxic selenium and hydrogen selenide fumes, and if heated to dryness, copper fume may be produced.


Extinguishing Media: No specific recommendation. Use media to suppress surrounding fire.


Fire Fighting Measures, continued


Fire Fighting Instructions: Do not enter confined fire space without proper personal protection. Use approved positive pressure self-contained breathing apparatus. Do not use water except as

a fog. Cool surrounding containers with water spray. Prevent runoff to sewers and waterways. Treat as dilute nitric acid and selenious acid solution. May produce highly toxic selenium fumes and Hydrogen Selenide. Flammable hydrogen gas may be liberated from contact with some metals. Toxic fumes of SOx may be released above 400ºC



HEALTH: 3  - Very short exposure could cause serious temporary or residual injury requiring immediate attention.

FLAMMABILITY: 0  - Will not burn.

REACTIVITY: 1  - Normally stable but can become unstable at elevated temperatures and pressures, or may react non-violently with water.

SPECIFIC HAZARDS: Corrosive, oxidizing material


6.   Accidental Release Measures


Personal Protection: Evacuate unnecessary personnel from spill area. Wear appropriate personal protective equipment. Ventilate area. Do not touch spilled product without proper personal protection. See Section 8 for proper protective equipment to be worn while cleaning an accidental spill.

Environmental Precautions: Implement spill control plan. Stop or reduce leak if safe to do so. Prevent from entering sanitary or storm sewers, waterways, or confined spaces. Use inert materials such as earth or sand to form dike. Keep from contacting aquatic life.

Remedial Measures: Restrict access to area until completion of cleanup. Ensure cleanup is conducted by trained personnel only. Use all appropriate personal protective equipment. For small spills: absorb with neutralizing materials such as soda ash or lime and collect in sealed containers. Flush area with water. For large spills, contain and collect spilled material if possible. Notify government occupational health and safety and environmental authorities as per applicable regulations.

7.   Handling and Storage


Handling Procedures: Prevent release of vapor or mist into workplace air. Ensure adequate ventilation. Have emergency equipment readily available. If diluting, slowly add product to the water to avoid boiling or splattering. Keep containers closed when not in use. Wash face and hands thoroughly after handling and before eating, drinking, or using tobacco products.

Storage: Store in a cool, dry, well ventilated area, out of direct sunlight and away from heat sources.  Store away from incompatible materials such as oxidizing materials, reducing materials, and strong bases. Keep storage area separate from populated work areas.   


8.   Exposure Controls, Personal Protection


Engineering Controls: Use general or local exhaust ventilation to maintain exposure below the exposure limits.

Respiratory Protection: If respiratory protection is required, NIOSH recommends for nitric acid vapour or mist in air:

Up to 25 ppm: Chemical cartridge respirator with inorganic acid cartridge(s), powered air-purifying respirator with appropriate cartridge(s), Supplied Air Respirator (SAR), or a full face-piece SCBA.

Exposure Controls, Personal Protection, continued


IDLH Conditions (25 ppm) or Planned Entry in Unknown Concentrations: Positive pressure, full face-piece SCBA, or positive pressure full face-piece SAR with an auxiliary positive pressure SCBA.

Escape: Gas mask with canister, or escape type SCBA.

NOTE: Air purifying respirators do not protect against oxygen deficient atmospheres.

Skin protection: Wear impervious gloves and boots and/or other protective clothing according to circumstances. 

Eye and Face Protection: Eye protection is required. Chemical safety goggles are recommended. The wearing of contact lenses is not recommended.

Footwear: As required by worksite rules.

Other: Have a safety shower and eye wash station readily available in the immediate work area.
