| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin, eyes and respiratory tract. Danger of serious damage to health by prolonged exposure through inhalation. Toxic if swallowed. May cause cancer by inhalation. |
| Primary Routes of Exposure: | Ingestion, eyes, inhalation |
| Eye Contact: | Causes slight to mild irritation of the eyes. |
| Skin Contact: | Causes irritation and an allergic reaction of the skin. Wounds contaminated with beryllium are slow to heal. |
| Inhalation: | Danger of serious damage to health by prolonged exposure through inhalation. May cause cancer by inhalation. |
| Ingestion: | Toxic if swallowed. May cause gastrointestinal irritation, nausea, and vomiting. |
| Acute Health Effects: | Irritating to skin, eyes and respiratory tract. Toxic if swallowed. Danger of serious damage to health by prolonged exposure through inhalation. |
| Chronic Health Effects: | Prolonged exposure to dust can cause chronic berylliosis of the lungs resulting in diminished lung function. May cause cancer by inhalation. |
| NTP: | Yes |
| IARC: | Yes |
| OSHA: | No |
| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area immediately with water. Remove contaminated clothing if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |
