3.   Hazards Identification


Routes of Entry: (under normal conditions of use)


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


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.

Skin Contact: Solution may irritate the skin and area under nails. May lead to dermatitis and sensitization.

Eye Contact: Selenium in solution will irritate eyes. An allergic reaction may occur, as redness and/or puffiness. 

Ingestion: Will irritate mouth, throat, esophagus, and stomach. May cause nausea, pallor, coated tongue, and gastrointestinal disorders.





Hazards Identification, continued


Effects of Long-Term (Chronic) Exposure:

The chronic effects may be dermatitis and skin sensitization from skin contact. Chronic toxicity may present itself as respiratory tract irritation, gastrointestinal symptoms, fatigue, pallor, and metallic taste. Garlic breath is a sign of selenium absorption.

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: This product is not expected to present an inhalation hazard at ambient conditions. 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: Rinse mouth with water. Dilute contents of stomach with 1-2 glasses of water. Do NOT induce vomiting. 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: 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 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 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




Fire Fighting Measures, continued



HEALTH: 2  - Short exposure could cause temporary or residual injury

FLAMMABILITY: 0  - Will not burn.

REACTIVITY: 0  - Normally stable but can become unstable at elevated temperatures and pressures, or may react non-violently with water.



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. Contain spillage and neutralize with soda ash. Mop up with absorbent material and dispose of in TC approved waste containers. Keep non-neutralized materials from spilling into sewers, storm drains, surface water, and soil. Comply with all applicable governmental regulations on spill reporting and handling and disposal of waste.

7.   Handling and Storage


Handling Procedures: Prevent release of vapor or mist into workplace air. Ensure adequate ventilation. Have emergency equipment readily available. 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 active metals and alkalis. Keep storage area separate from populated work areas or food.   


8.   Exposure Controls, Personal Protection


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

Respiratory Protection: Use a NIOSH approved dust/fume respirator for acid gases when appropriate.

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.
