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 If a worker on a scaffold can fall more than 10 feet, they must be protected by guardrails and/or personal fall arrest systems (PFAS). The type of fall protection required will depend upon: The type of scaffold The four main causes of crane accidents are contact with power lines, overturns, falls and mechanical failure. Two other errors mentioned in this module that often lead to trouble are: Improper maintenance and failure to conduct regular inspections No modifications or additions that affect the capacity or safe operation of a crane or derrick should ever be made without: The manufacturer's written approval, which should be kept on file Truck-mounted and rough terrain cranes are both forms of a mobile crane, and both use which of the following to increase their stability? outriggers Rated load capacities, recommended operating speeds, and special hazard warnings or instructions must be: Conspicuously posted on the crane, where the crane operator can see them while he is at his control station The four lifting principles that govern a crane's mobility and safety during lifting operations are: Center of gravity, leverage, stability and structural integrity Employees working in the vicinity of a crane must take care to avoid what kind of accident? "Struck by" Personnel hoisting platforms must be designed by: A qualified engineer, or another competent specialist qualified in structural design True or False: Only personnel instructed in the requirements of the standard and the task to be performed - along with their tools, equipment and materials needed for the job - are allowed on the platform. True If the hoist tower is not enclosed, the hoist platform or car must be totally enclosed on all sides for the full height between the floor and: The overhead protective covering The greatest hazards posed by hand tools result from: misuse and improper maintenance Power tools should never be carried by the cord or hose or be yanked from a receptacle by the cord or hose; and cords and hoses should be kept away from: Heat, oil, sharp edges Sharp, abrasive, pinching, or otherwise hazardous moving parts of power tools: Must have protective guard to prevent contact with workers Before an abrasive wheel is mounted, it should be inspected closely and: Sound- or ring-tested to ensure that it is free from cracks or defects Neither the operator nor anyone else should ever stand directly in front of the wheel of an abrasive power tool as it accelerates to full operating speed. Why? Because there is always the chance that the wheel wasn't sound and could disintegrate or explode Pneumatic tools are powered by: Compressed air Powder-actuated tools are extremely dangerous, with a "firing" mechanism similar to that of: A loaded gun If a powder-actuated tool misfires, the employee should: Wait at least 30 seconds, then try firing again All jacks - lever and ratchet jacks, screw jacks, and hydraulic jacks - must have a device that stops them from: Jacking up too high (a stop indicator) OSHA defines a trench as: A narrow excavation made below the surface of the ground in which the depth is greater than the width - with the width not to exceed 15 feet True or False: There is usually some form of warning before a cave-in. False 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 Under the new HAZCOM/GHS requirements for Safety Data Sheets (SDS's) they must now have 16 total Sections. true Employers must provide employees with effective information and training on hazardous chemicals in their work area: -- At the time of their initial assignment -- Whenever a new hazardous chemical is introduced into their work area The noise exposure measurement your employer makes must include all continuous, intermittent and ______ noise within a range of 80 dB to 130 dB. Impulsive To determine whether employees need hearing protection, employers have to consider: -- The loudness of the noise, as measured in decibels -- The duration of exposure to the noise -- How many sources generate loud noises Audiometric testing monitors an employee's hearing: over time Acute silicosis occurs after a few months or as long as 2 years following exposures to ________ concentrations of respirable crystalline silica. extremely high Symptoms of silicosis ____________ , so workers should have a chest x-ray to see if there is lung damage. may or may not be obvious Which of the following is an element of a hearing conservation program? -- Engineering and Administrative Controls -- Noise monitoring -- Hearing protection to be used Using cranes to hoist material can have serious consequences if the process is not performed properly. Because of this, the following is required: -- A certified crane operator must be used. -- Rigging must be inspected prior to use, be in good shape and have the tag attached. -- A Qualified Rigger is responsible for connecting the crane to the material to be hoisted. True or False: Once a fall protection device has been inspected by a competent person and deemed safe for use by an employee, it is up to the employee to inspect it regularly and ensure that it still meets OSHA requirements. False True or False: Before the advent of OSHA, a cohesive system of separate rules existed that effectively governed the American workplace. These rules were combined under the umbrella of OSHA. False Which industries are employees potentially exposed to silica dust: -- Stone and glass industries -- Construction -- Mining industries Anytime an adapter is used to accommodate a two-hole receptacle, the adapter wire must: be attached to known ground If a worker on a scaffold can fall more than 10 feet: They must be protected by guardrails and/or personal fall arrest systems (PFAS) In noisy jobsites, these are often used to provide instructions to crane and derrick operators: Hand signals Since its implementation in 1971, OSHA has: -- Helped cut work-related fatalities nearly in half and cut excavation and trenching fatalities by more than a third --Helped reduce workplace injuries and illnesses by 40 percent (Your Answer) -- Almost eliminated brown-lung disease from the textile industry Prior to starting all demolition operations, OSHA 1926.850 (a) requires that an engineering survey of the structure be conducted by a competent person. The purpose of this survey is: determine the condition of the structure so that measures can be taken, if necessary, to prevent the premature collapse of any portion of the structure Two of the main differences between the hydraulic rough terrain crane and the crawler lattice boom friction crane are: boom hoist, load line controls True or False: Employers must provide a training program that teaches employees who might be exposed to fall hazards how to recognize such hazards and how to minimize them, and must also prepare a written certification that identifies the employee trained and the date of the training. true The most effective way to prevent exposure to crystalline silica is: Substitution of a product that contains silica with a product that doesn't contain silica
