Hazards and Protection.
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.
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.
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive pressure-mode. Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode beryllium and beryllium compounds (as Be).
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.
Avoid contact with acids, caustics, chlorinated hydrocarbons, oxidizers, molten lithium. Beryllium and beryllium compounds (as be)
Extinguish using agent most appropriate for surrounding fire.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with metals may evolve flammable hydrogen gas.
Fire may produce irritating, corrosive and/or toxic gases.
IDHL: NIOSH considers beryllium and beryllium compounds (as Be) to be potential
G-A1, I-1, N-1, CP65
Fatigue, headache, and seizures may occur.
Nausea, vomiting, and a metallic taste may be noted.
Acute - irritation, pneumonitis, dyspnea, pulmonary edema.
Acute - skin irritation, contact dermatitis
Beryllium is thought to be poorly absorbed from the gut and usually presents no hazard if ingested. Some compounds may be irritating and dilution is recommended. 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).
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Chronic granulomas are removed surgically.
Immediately flush with running water for at least 20 minutes.
