One standard set by OSHA is that all construction employers must provide fire extinguishers and other forms of fire protection/prevention all throughout the construction job site. Another standard set up by OSHA is the availability of clean drinking water and water available for cleanup after chemical spills/accidents. A third standard OSHA established is the idea that all places of employment must have adequate lighting to ensure that workers do not injure themself such as falling into a hole or off a raised ledge. There are many more standards OSHA set in place, and OSHA sends out inspectors to make sure the standards are being enforced.
