Maintenance of Tools and Equipment.
To ensure that workers are not in danger, all vehicles, tools, and equipment must be kept in good working order. Vehicles, tools, machines, and equipment must all pass inspections before being used according to construction rules.
In order to maintain tools, equipment, machines, and vehicles in a safe, operable condition that reduces downtime and increases productivity, preventive maintenance is the methodical care and protection of these items. We must always be conscious of the fact that maintenance duties themselves may be dangerous and cause harm.
The majority of manufacturers can offer maintenance plans for their products. Due to the capital investment and/or lease agreements, large businesses with a fleet of cars and/or equipment often have an extensive maintenance programme. Equipment leasing is an option for smaller businesses, and the leasing contract may also include maintenance services.
