Attempt this task only with full permission from your supervisor/instructor and follow all the guidelines exactly. Caution: If you are working in an area where there could be brake dust present (may contain asbestos, which has been determined to cause cancer when inhaled or ingested), wear and use all OSHA-approved asbestos protective/removal equipment. Lifting equipment such as vehicle jacks and stands, vehicle hoists, and engine hoists are important tools that increase productivity and make the job easier. However, they can also cause severe injury or death if used improperly. Make sure you follow the manufacturer s operation procedures. Also make sure you have your supervisor/instructor s permission to use any particular type of lifting equipment. Comply with personal and environmental safety practices associated with clothing; eye protection; hand tools; power equipment; proper ventilation; and the handling, storage, and disposal of chemicals/materials in accordance with federal, state, and local regulations.
