Section 7. Handling and storage <br />Precautions for safe handling <br />Protective measures : Put on appropriate personal protective equipment (see Section 8). Contains gas <br />under pressure. Avoid contact with eyes, skin and clothing. Avoid breathing gas. <br />Use only with adequate ventilation. Wear appropriate respirator when ven tilation is <br />inadequate. Do not enter storage areas and confined spaces unless adequately <br />ventilated. Store and use away from heat, sparks, open flame or any other ignition <br />source. Use explosion-proof electrical (ventilating, lighting and material handling ) <br />equipment. Use only non-sparking tools. Empty containers retain product residue <br />and can be hazardous. Do not puncture or incinerate container. Use equipment <br />rated for cylinder pressure. Close valve after each use and when empty. Protect <br />cylinders from physical damage; do not drag, roll, slide, or drop. Use a suitable hand <br />truck for cylinder movement. <br />Advice on general : Eating, drinking and smoking should be prohibited in areas where this material is <br />occupational hygiene handled, stored and processed. Workers should wash hands and face before eating, <br />drinking and smoking. Remove contaminated clothing and protective equipment <br />before entering eating areas. See also Section 8 for additional information on <br />hygiene measures. <br />Conditions for safe : Store in accordance with local regulations. Store in a segregated and approved <br />storage, including any area. Store away from direct sunlight in a dry, cool and well -ventilated area, away <br />Incompatibilities from incompatible materials (see Section 10). Eliminate all ignition sources. Keep <br />container tightly closed and sealed until ready for use. Cylinders should be stored <br />upright, with valve protection cap in place, and firmly secured to prevent falling or <br />being knocked over. Cylinder temperatures should not exceed 52 °C (125 °F). <br />Section 8. Exposure controls/personal protection <br />Control parameters <br />Occupational exposure limits <br />Ingredient name Exposure limits <br />Propane ACGIH TLV (United States, 3/2012). <br />TWA: 1000 ppm 8 hours. <br />NIOSH REL (United States, 1/2013). <br />TWA: 1800 mg/m³ 10 hours. <br />TWA: 1000 ppm 10 hours. <br />OSHA PEL (United States, 6/2010). <br />TWA: 1800 mg/m³ 8 hours. <br />TWA: 1000 ppm 8 hours. <br />OSHA PEL 1989 (United States, 3/1989). <br />TWA: 1800 mg/m³ 8 hours. <br />TWA: 1000 ppm 8 hours. <br /> <br />Appropriate engineering : Use only with adequate ventilation. Use process enclosures, local exhaust <br />controls ventilation or other engineering controls to keep worker exposure to airborne <br />contaminants below any recommended or statutory limits. The engineering controls <br />also need to keep gas, vapor or dust concentrations below any lower explosive <br />limits. Use explosion-proof ventilation equipment. <br />Environmental exposure : Emissions from ventilation or work process equipment should be checked to ensur e <br />controls they comply with the requirements of environmental protection legislation. In some <br />cases, fume scrubbers, filters or engineering modifications to the process equipment <br />will be necessary to reduce emissions to acceptable levels. <br />Individual protection measures <br />Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before <br />eating, smoking and using the lavatory and at the end of the working period. <br />Appropriate techniques should be used to remove potentially contaminated clothing. <br />Wash contaminated clothing before reusing. Ensure that eyewash stations and <br />safety showers are close to the workstation location. <br />
