Conditions to Avoid: N/A
Steps to be taken in case material is released: In case of release to the environment, report spills to the National Response Center 1 -800-424-8802
Suggested Local Action: Contain spill. Prevent large quantities from contacting vegetation or domestic and natural water sources. If material is not contaminated place in appropriate DOT approved containers for disposal.
Waste Disposal Method: (ERA Waste identification #: N/A) If contaminated with other materials, the nature and extent of contamination may require the use of specialized disposal methods. If disposal is necessary, comply with all local, state, and federal regulations. Contact your local EPA office for help.
For Hazardous Waste Regulation: call 1-800-424-9346 – The RCRA Hotline.
Inhalation: Over exposure may produce irritation of the mucous membranes, nose, throat, coughing and shortness of breath. In addition it may contain small amounts of silica particles less than 5mm in diameter. These silica particles are capable of causing silicosis if inhaled in high enough concentrations over an extended period of time. The principal manifestation of silicosis if difficulty in breathing. This condition can progress to dry cough, shortness of breath on exertion, decreased lung function and pulmonary fibrosis.
Skin Contact: May cause irritation, particular on damp skin. Repeated or prolonged contact could lead to dermatitis. Wash affected area with mild soap and water.
Eye Contact: May cause irritation and conjunctivitis. Flush with large amounts of water for at least 15 minutes, while rolling eyeball and lifting eyelid. Get medical attention.
Ingestion: Give milk, egg whites, or water to�
Inhalation: Remove from exposure. If breathing is difficult or has stopped, administer artificial respiration or oxygen as indicated. Immediately seek medical aid.
Skin Contact: Wash thoroughly with soap and water. Seek medical aid.
Eye Contact: Flush immediately with large amounts of water, lifting the lower and upper lids occasionally. Seed medical help.
Ingestion: Give 1 -2 large glasses of water or milk. Immediately seek medical aid. Never give liquids to an unconscious person.
Carcinogenicity: Not listed as a carcinogen by NTP, (ARC, or OSHA)
Routes of Entry: Inhalation, Skin and Eye Contact if handled in such a manner that dust is generated.
Effects of Overexposure: As sold, this product is not anticipated to pose an acute or significant health hazard. However, if subjected to dust generating processes, adverse health effects may occur.
Calcium oxide is caustic to living tissue. Overexposure may cause irritation of the eyes, skin, and upper respiratory tract Inflammation of the respiratory tract, ulceration and perforation of the nasal septum, bronchitis and pneumonia have also bee attributed to inhalation of calcium oxide dust. Eye contact may cause conjunctivitis, corneal ulceration. Skin contact may cause skin inflammation and ulceration.
Medical Conditions Aggravated by Exposure: Chronic disease and disorders of the respiratory system and skin.
Respiratory: Respiratory protection approved by NIOSH/MSHA for protection against dust should be used to avoid inhalation. Appropriate respiration selection depends on the type and magnitude of exposure.
Skin: Clean, body-covering clothing should be worn to prevent irritation in situation where direct contact with product may occur or dust levels are excessive.
Eyes: Employees should be required to wear chemical safety splash goggles in situations where direct contact with the product may result in eye injury.
Ventilation: Local exhaust ventilation should be used to control worker exposure to below recommended Permissible Exposure Levels (PEL).
Other Protective Equipment: Emergency eye wash stations and deluge safety showers should be available in the work areas.
Precaution to be taken in handling and storage: Store in a cool, dry location. Keep out of reach of children and pets.
