4. Hazards

What are the causes of accidents involving hand or powered tools?

Most hand and powered tools are made of solid metal or plastic material, this solid body may accidentally fall or be ejected or pushed against human body parts like hand, face or foot causing impact injuries.

Solid metal tools can create sparks when they strike another hard surface, causing fires if flammables are nearby.

"Electrically" powered tools that use either AC or DC power can cause unwanted ignition and fire or explosion if they used in classified area where flammable vapours at appropriate concentrations exist. 

AC powered tools have the potential to cause electrocution and shock if incorrectly handled or maintained. 

Many tools have sharp surface like saws, cutters and blades causing cut injuries.

In the same way, many tools have pointed head that can penetrate the body like screw driver, nail, needle nose pliers.
