Which of these is required if the worker's body, hands or clothing may come into contact with moving parts? - ✔✔Provide guards on power tools and other equipment with moving parts The critical first step in developing a comprehensive safety and health program is to identify physical and health hazards at a work site. This process is known as: - ✔✔A hazard assessment OSHA requires that many categories of PPE meet or be equivalent to standards developed by: - ✔✔The American National Standards Institute (ANSI) You should have head protection if which of the following apply to your job? - ✔✔-- Objects might fall from above -- There are low-hanging pipes or beams -- There are exposed electrical hazards In general, head protection should do which of the following? - ✔✔-- Resist penetration by objects and absorb the shock of a blow -- Be water-resistant and slow burning -- Have clear instructions explaining proper adjustment and replacement of the suspension and headband There might be one pair of protective eyewear for your task or station, rather than individual eyewear for each employee. If this is the approach at your job site, then: - ✔✔You must clean and disinfect the eyewear between each use A noise level of 95 dB is ______ than the lowest level at which hearing protection is required (85 dB), and your exposure should be limited to six hours or less. - ✔✔Ten times louder than Safety footwear has to meet minimum compression and impact performance standards, set by: - ✔✔ASTM F-2412-2005 Gloves that are chemically resistant are usually made from: - ✔✔rubber or plastic True or False: Full-body protection is sometimes made from materials such as duck, paper-like fiber, or rubberized fabrics, depending upon the hazard. - ✔✔True Before the start of each work shift, it is mandatory that: - ✔✔A competent person inspects the scaffold before the start of each work shift The first step in building a scaffold is to: - ✔✔Conduct a site inspection A scaffold must be erected "plumb, square, and level," because: - ✔✔If a scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift, potentially causing the overloading of one leg and the eventual collapse of the scaffold OSHA 1926.454(c) states: When an employer has reason to believe that an employee lacks the skill or understanding needed for safe work involving the erection, use or dismantling of scaffolds, the employer shall: - ✔✔Retrain each such employee so that the requisite proficiency is regained When dismantling a scaffold, all work should be conducted: - ✔✔From the top down Tube and coupler scaffolds over 125 feet high must be designed by: - ✔✔registered professional engineer What type of scaffold - other than the tube and coupler scaffold - is ideal for use around complex structures? - ✔✔a system scaffold This scaffold is simply a rope attached to a harness with an assembly like a boatswain's chair for the worker to sit in. - ✔✔Suspension scaffold OSHA requires that all excavations in which employees could potentially be exposed to cave-ins be protected by one or more of the following three methods: - ✔✔Sloping, benching, shoring, shielding The formula for all simple slope excavations 20 feet (6.11 meters) or less deep states that for every foot of depth, the trench must be excavated back: - ✔✔1 and 1/2 feet Trench boxes or shields must be designed or approved by: - ✔✔a registered professional engineer Shoring or shielding is most often used when: - ✔✔The location or the depth of the excavation makes sloping back to the maximum allowable slope impractical As mentioned in this module, in addition to cave-ins and related hazards, workers involved in excavation work also are exposed to hazards involving: - ✔✔Falls, falling loads and mobile equipment Employees are prohibited from working above other employees on the face of a sloped or benched excavation unless: - ✔✔Workers on lower level have overhead protection from falling objects To prevent surface water from entering an excavation and to provide adequate drainage of the adjacent area, OSHA standards require the use of: - ✔✔Water removal equipment, diversion ditches, dikes, or other suitable methods In the case of materials handling, storage, use and disposal, remember that the main hazards are injuries from: - ✔✔-- Improper lifting and carrying -- Being struck by materials or caught in pinch points -- Being crushed by improperly stored materials Because the number of injuries from operating powered industrial trucks was on the rise, the OSHA standard for Powered Industrial Trucks was revised March 1, 1999.
