Verifying Safeguards Picture This

What is wrong in this picture? There is a man doing multiple unsafe procedures in this picture, first he using a grinding wheel without any guard, second all the sparks coming out of the machine are falling into two oxygen cylinders which makes it too dangerous, third he is not wearing any facial mask or glasses to protect his eyes from those sparks and finally there is a solvent knob close to his work area. All of those unsafe procedures are strongly dangerous that can result in a horrible disaster with many injuries, burns and even death.

Never use a machine without the guard which is provided for protection. Check the machine for any kind of crack or damage before using the grinder.

Never use a machine without wearing all the personal protective equipment and clothing such as goggles, helmets, masks, ear protection, gloves, leather aprons etc. Also ensure that the personal protective equipment and tools are in proper condition before using them.

Finally, make sure all safeguards are in place to avoid a catastrophe, check your work area before start working, follow all safety work practices and ensure your personal safety.
