Welding and Hot Work, such as brazing or grinding present a significant opportunity for fire and injury. All precautions of this program must be applied prior to commencing any welding or hot work by company employees or contractors. Hot work presents an increased risk of fire and explosion hazards because it is most often performed in confined and enclosed spaces.

Safe cutting and grinding practices in confined spaces is not just about assessing risks beforehand, but means continually monitoring the area for hazardous substances until the work is done. Thorough evaluations of the situation, job requirement and safety procedures will significantly reduce the risk of injury or fatality.

Welding and cutting operations shall ideally be conducted in a separate, well ventilated ... Confined Spaces - Atmospheric testing must be performed as well

Use of chemicals, painting, cleaning, grinding or sanding all create atmospheric hazards that can cause injury or illness without adequate ventilation or other controls. Hot work (e.g., welding, cutting, grinding, or brazing) in a confined space may release toxic gases and fumes.

3. Reaching hard-to-access welds or spaces Whether grinding a fillet weld or a butt weld in a confined area, different weld types and space constraints can result in different challenges for cutting and grinding. A butt weld is often easier if there are no …

Concrete cutting and concrete grinding are very dusty jobs in the construction industry, both posing a serious health risk to masons. Masonry blocks, bricks, and concrete slabs contain concentrated amounts of crystalline silica. When these materials are dry-cut they release silica containing dust into the workers' breathing zone. Regular exposure to this hazardous dust can

Issued: 6 May 2011 Last Updated: 29 April 2011. Purpose. The purpose of this safety alert is to provide practical guidance to minimise health and safety risks associated with the danger of grinding, cutting and welding in, on and around confined spaces and compartments such as tanks, containers, vessels and other enclosed structures, which have contained flammable or combustible …

3. Make sure adequate ventilation is available and used when welding or cutting in confined areas. 4. Remove rust inhibitors, paints, degreasers, and other coatings prior to performing hot work. Ventilation . 1. When welding in a confined or enclosed space, provide mechanical ventilation as needed. 2.

Welding or Cutting in Confined Spaces. Confined space procedures must be followed when performing work in a confined space. When working in poorly ventilated spaces, exposure to air contaminants generated by welding or cutting must be controlled by ventilation, respiratory protection, or a combination of the two.

When completing construction work in a confined space, safety is always a significant concern. However, when the material worked with is concrete, there are new risks introduced. It is vital that any construction crew working with concrete in confined spaces follows the tips below to remain safe. First, Know What a Confined Space Is

In confined spaces or indoors, welding or cutting operations involving cadmium-bearing or cadmium-coated base metals must be done using local exhaust ventilation or airline respirators unless atmospheric tests under the most adverse conditions show that employee exposure is within the acceptable concentrations specified by 29 CFR 1910.1000.

A confined space is an area with limited access which normally as little or not ventilation. Dangerous concentrations of toxic fumes and gasses can build up very quickly. Suffocation can occur because welding, brazing and cutting can use up or displace oxygen in the air.
