There are several things to consider when working on various materials to make the final product look great and last longer. The kind of material to be used is not the only factor that should be considered but also its quality. They must be clean before, during and after production so they can keep their pristine appearance even after many years.
But sometimes cleaning them with soap and water is not enough to remove all the contaminants that have stuck on them. This is when calling the abrasive blasting Los Angeles CA companies is advisable to do this job for you. Or you could just purchase the equipment and media they use to clean your particular items.
More known commonly as sandblasting, this operation propels a stream containing of abrasive materials forcibly against a surface. This remove the contaminants as well as shape, smooth rough surfaces or roughen smooth ones. A pressurized fluid, usually a centrifugal wheel or compressed air is used in propelling the media and several variants are there for this process depending on the abrasiveness.
Using this method for cleaning surfaces is better since the great force and media used by the machine enables it to remove rust and other contaminants. Doing so is important before applying surface coating protection to these things so they would last longer. If they were not cleaned, the coating might not stick properly which could result into a bad quality work.
Safety must be observed when working on this operation since there are risks with the media being inhaled or wounding the operator. They should wear the proper protective gear which provides full coverage all over their body. Though the abrasive materials used may not all be hazardous but there are some that are like heavy metals or silica.
There is also a risk of getting burns from the projections causing eye or skin lesions and falling due to the round shot on the ground which are scattered. Other risks include heat exhaustion, exposure to noise excessively or hazardous dusts and creation of explosive atmosphere. Though blasting rooms and equipment have been adapted to prevent these dangers from affecting the operator.
Safety equipment typically used by operators include positive pressure blast helmet or hood which has a system for head suspension. This allows the device in moving together with the head of the person wearing it. It also has an air feed hose attached to a supply and a view window that has lens protection or removable lens.
The air supply is attached to a hose connected to the helmet and is mandated by OSHA in protecting the worker against hazardous gases. It includes an air filtration, carbon monoxide monitor and alarm, and a pressure regulator. The operator would also need a hearing protection while working such as ear plugs or ear muffs.
Body protection is also important and it varies depending on the application. But this usually includes of chaps, leather coat or overalls, and gloves. Following this safety guidelines is vital to prevent them from getting sick and possibly dying due to complications.
