Always seek medical advice after the first aid treatment.
| Inhalation | Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician immediately. |
| Ingestion | DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Call a physician immediately. |
| Skin Contact | In case of contact with Calcium Hydroxide or Slaked Lime , wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Call a physician immediately. |
| Eye Contact | Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Call a physician immediately. |
| Fire | Not considered to be a fire hazard. |
| Explosion | Not considered to be an explosion hazard |
| Fire Extinguishing Media | Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Use any means suitable for extinguishing surrounding fire. Special hazards arising from the substance or mixture: Calcium oxide |
| Special Information | Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and clothing. |
| Personal precautions, protective equipment, and emergency procedures | Ventilate area of leak or spill. Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material. |
| Environmental precautions: | Do not let the product enter drains, soil, or water sources. |
| Methods and materials used for containment Cleanup procedures and Storage | Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep-up and remove to an approved disposal container. Use method that does not generate dust. Do not flush caustic residues to the sewer. Carefully pick up solid with minimum of dusting and collect in metal container with covers with disposal. The trace amount of residue of Calcium Hydroxide or Slaked Lime may be flushed down the drain as per law. |
| Precautions for safe handling: | Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces. |
| Conditions for safe storage, including any incompatibilities: | Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes.Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents and acids. Avoid maleic anhydride, nitro ethane, nitro methane, nitro paraffin, nitro propane, phosphorus. |
| Airborne Exposure Limits: | OSHA Permissible Exposure Limit (PEL): 15 mg/m3 (total dust), 5 mg/m3 (respirable fraction) |
| ACGIH Threshold Limit Value (TLV) | 5 mg/m3 CALCIUM HYDROXIDE (LIME) WEL (Work Place Exposure Limit) 5 mg/m3 |
| Ventilation System | A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. |
| Personal Respirators (NIOSH Approved) | If the exposure limit is exceeded and engineering controls are not feasible, a full face piece particulate respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids. glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen- deficient atmospheres. |
| Skin Protection | Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. |
| Eye Protection | Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area. |
