Drilling » Safety Data Sheet (SDS)
This Safety Data Sheet (SDS) contains information on the use and procedures for handling hazardous chemicals (See below for an example of SDS for Caustic Soda). There are safety data sheets for all hazardous chemicals used in the drilling industry. Safety Data sheets must be supplied to the employer by the manufacturer and/or supplier each time the chemical is introduced into the workplace. The employer must maintain all SDS and ensure they are immediately available. See 29 CFR 1910 Subpart Z, Toxic and Hazardous Substances, Hazard Communication [29 CFR 1910.1200].

FIRST AID MEASURES
- GENERAL: Persons seeking medical attention should carry a copy of this SDS with them.
- INHALATION: Move the exposed person to fresh air at once. Perform artificial respiration if breathing has stopped. Get medical attention.
- INGESTION: Drink a couple of glasses water or milk. Do NOT induce vomiting unless directed to do so by a physician. Never give anything by mouth to an unconscious person. Get medical attention.
- SKIN: Wash skin thoroughly with soap and water. Remove contaminated clothing. Get medical attention if any discomfort continues.
-
EYES: Promptly wash eyes with lots of water while lifting the eye lids. Continue to rinse for at least 15 minutes. Get medical attention if any discomfort continues.

- PROTECTIVE EQUIPMENT:
- ENGINEERING CONTROLS: Use appropriate engineering controls such as exhaust ventilation and process enclosure to reduce air contamination and keep worker exposure below the applicable limits.
- VENTILATION: Supply natural or mechanical ventilation adequate to exhaust airborne product and keep exposures below the applicable limits.
- RESPIRATORS: Use at least a NIOSH-approved N95 half-mask disposable or reuseable particulate respirator. In work environments containing oil mist/aerosol, use at least a NIOSH-approved P95 half-mask disposable or reuseable particulate respirator.
- PROTECTIVE GLOVES: Use gauntlet type rubber gloves.
- EYE PROTECTION: Use tight-fitting goggles if dust is generated. Wear splash-proof eye goggles to prevent any possibility of eye contact.
- PROTECTIVE CLOTHING: Wear appropriate clothing to prevent any possibility of skin contact. Provide eyewash station and safety shower.
-
HYGIENIC WORK PRACTICES: Wash promptly with soap and water if skin becomes contaminated. Change work clothing daily if there is any possibility of contamination.
