Multi-employer Worksites When more than one employer operates at a single site, OSHA considers it a multi-employer worksite. A construction site is an example of a multi-employer worksite with multiple contractors assigned the work, but not all at the same time. Employers at multi-employer worksites need to know their responsibilities, assigned roles, and accountability for employee health and safety. Note that a multi-employer worksite differs from a dual-employer worksite, where an employee has two employers at the same time. For example, a temporary agency employee that is assigned to another employer’s worksite. On multi-employer worksites, all of the employers must work together...

Personal Protective Equipment - Concrete Construction Concrete construction has unique requirements for the need of personal protective equipment (also called PPE). Today we are going to discuss the various types of PPE and why. Guide for Discussion Construction Common Some sort of head gear. If there is a danger of falling objects, wear a hard hat. If working in cold weather, wear a hat to keep the body warm. Eye protection. Wear safety glasses or goggles when pouring concrete. That way any splashing concrete stays out of your eyes. Gloves. It makes common sense to protect our hands as much as possible. Wearing...

Masonry and Concrete Saws Masonry saws are used to cut tiles, bricks, and blocks of stone, concrete, and other materials. Concrete saws are used to cut channels or openings through concrete blocks, slabs, and walls. Both types of saws can be hand-held, mounted on a stand, or wheeled by hand or motor and may be powered by electricity, compressed air, or fuel. Working with saws can expose workers to hazards such as cutting blades, kick-back, push-back, pull-ins, and dust; training and proper work practices are the key to safety. Workers require training on the safe use of masonry and concrete saws. Cutting...

Loading Dock Safety While a loading dock is an important utility infrastructure commonly found in commercial and industrial buildings, it can be a potentially dangerous place for anyone that works on or around the area. From 2004 to 2014, the Occupational Safety and Health Administration (OSHA) investigated 209 injuries and nearly half were fatalities. Loading Dock Hazards The loading dock area must be inspected regularly to identify potential hazards that may include: Slips, trips and falls caused by floor conditions, poor housekeeping, or dock edge. Forklifts overturning. Pedestrian and powered truck collision. Trailer creep, which can cause a gap between the trailer and...

Sheet Metal Worker Safety Sheet metal workers make, install, and maintain heating, ventilation and air duct systems (HVAC); metal building equipment (roofs, siding, gutters, downspouts, counters, and back splashes); signs, and vehicles. Factory and fabrication shop workers cut raw materials, then form and fasten them into end products for installation at construction sites. Varied sheet metal tools, tasks, and shop, factory, and construction locations require specialized training in hazards, equipment, and safe work practices. Get training on chemical safety, building hazards (asbestos, lead, mold), ergonomics, good housekeeping, vehicle movement, and electrical safety. Provide extra training and good supervision to apprentices new to the job. Sheet...

Dust Explosions Dust Explosions - When combustible or non-combustible materials are broken down into fine dust or powders, they create a fire and explosion hazard affecting many operations and materials: sugar, flour, animal feed, plastics, paper, wood, rubber, furniture, textiles, pesticides, pharmaceuticals, paints and resins, dyes, coal, and metals. To prevent fires from dust explosions, control the “dust explosion pentagon.” This includes the traditional fire triangle: fuel, heat, and oxygen along with a dust cloud and enclosed space. Keep dust levels (fuel) in the workplace to a minimum with dust control and housekeeping. Control flame and ignition sources (heat) such as pilot...

Heavy Equipment Heavy equipment has been designed to handle very large volumes or large loads. As such, heavy equipment is powerful machines and can be dangerous to all around them if not operated correctly. It is important to remember the proper methods used to move them from one site to another, and how to work around them properly. Guide for Discussion General Rules When Heavy Equipment is Nearby Always remain alert to the equipment moving around you. Do not get near moving equipment unless necessary. Never ride on equipment unless it has been designed to carry you. This means it must have a...

Fatigue Can Lead to Accidents Sleep is an important factor in maintaining good health, well-being, memory, and the ability to think clearly. An adequate amount of sleep is defined as 7 to 9 hours of sleep each night. If you don’t get enough sleep due to work shifts, medical conditions, or other life factors, you could build up chronic sleep deprivation and fatigue. Fatigue is a safety concern because it is associated with higher injury and accident rates in the workplace. Fatigue reduces your attention and reaction time, which can cause you to make errors in judgment leading to mistakes at work....

Slips, Trips and Falls Maintain a safe environment with good housekeeping Don’t leave trip hazards in the work area Keep containers on the job for studs and nuts Constantly remove rubbish, scrap, and surplus materials Be on the lookout for foreign substances on the floors Cover or guard floor holes as soon as they are created Floor hole covers should support two times the weight of employees or equipment Survey the site before starting the day and continually audit the work space as work continues An unprotected edge 6 feet or more above a lower level should be protected by...

Arc Welding Safety Arc welders use a powerful electric arc to make and repair plain, coated, or treated metal items. Welders can be stationary, electric powered or portable, diesel/gas powered. Install electric-powered arc welders to code. To provide arc welding safety, ground equipment and place it on an independent circuit with the correct-sized fuse or circuit breaker. Overloading circuits or improper installation can lead to fire, a ground fault, or equipment failure. Mount a safety disconnect switch near the user work area. Operate diesel/gas powered arc welders in well-ventilated areas to control combustion fumes. Do not add fuel to the engine while...
