| Hazards and Protection. | |
| Storage | Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. |
| WHMIS | D1B D2B E |
| Handling | All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Protection | Wear appropriate protective gloves, clothing and goggles. |
| Respirators | Wear positive pressure self-contained breathing apparatus (SCBA). |
| Small spills/leaks | ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. |
| Stability | Stable under ordinary conditions of use and storage. May discolor on exposure to air. Polymerization may occur at high temperatures or in alkaline solutions (above pH 9), but it is not hazardous. |
| Incompatibilities | Avoid contact with strong oxidizers, strong bases. |
| Decomposition | When heated to decomposition it emits acrid smoke and fumes. |
| Fire. | ||||
| Flash Point,°C | 66 | |||
| Fire fighting | Wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. Use any means suitable for extinguishing surrounding fire. | |||
| Fire potential | This material will not burn until the water has evaporated. Residue can burn. | |||
| Hazards | When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | |||
| Combustion products | Fire may produce irritating, corrosive and/or toxic gases. | |||

| Exposure limit(s) | TLV: 0.2 ppm; 0.82 mg/m3 (ceiling values) (ACGIH 1992-1993). NIOSH REL: C 0.2 ppm (0.8 mg/m3) See Appendix C (Aldehydes) |
| Poison_Class | 3 |
| Exposure effects | Seizures and CNS depression were noted in animals given intravenous glutaraldehyde. |
| Ingestion | Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. May cause chemical burns of the mouth, throat, esophagus and stomach with discomfort or pain in the chest and abdomen. Aspiration into the lungs may occur during swallowing or vomiting, resulting in lung damage. |
| Inhalation | Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. Heating the solution may result in more severe irritant effects. |
| Skin | Causes irritation to skin. Symptoms include redness, itching, and pain. Prolonged contact may cause skin burns. May be absorbed through the skin with possible systemic effects. |
| Eyes | Corrosive! Vapors are irritating and may cause damage to the eyes. Contact may cause severe burns and permanent eye damage. |
First aid |
|
| Ingestion | Do not induce emesis - dilution: following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. |
| Inhalation | Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. |
| Skin | Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. |
| Eyes | Immediately flush with running water for at least 20 minutes. |
