Machine tools are powered industrial devices used to cut, drill, form, grind or shape materials. Common machine tools include drill presses, lathes, milling machines and pedestal grinders. Safe operation of machine tools is important to prevent injuries from moving parts, like crushed fingers or amputations. Proper safeguards, training, procedures and maintenance are needed to protect workers from preventable accidents caused by machine tools. Reaching into equipment without lockout/tagout, unauthorized use, missing guards and lack of training can lead to injuries from machine tools.

2. Machine Tools
• Heavy or non-portable power driven industrial
device used for cutting, drilling, forming,
grinding, or shaping of a material.

3. Types of Machine Tools
• There are several type of machine tool used in
the metal work industry. The most common
type are:
• Drill Press
• Lathe
• Milling Machine
• Pedestal Grinder

4. Safety
• Moving machine parts have the potential to
cause severe workplace injuries, such as crushed
fingers or hands, amputations, burns, or
blindness. Safeguards are essential for protecting
workers from these preventable injuries. Any
machine part, function, or process that may
cause injury must be safeguarded. When the
operation of a machine or accidental contact
injures the operator or others in the vicinity, the
hazards must be eliminated or controlled.

5. Causes of Machine Incidents
• Reaching in to “clear” equipment
• Not using Lockout/Tagout
• Unauthorized person doing maintenance or
using the machines
• Missing or loose machine guards
• Lack of training

6. Areas To Be Safeguarded
• Point of Operation
• Power Transmission Apparatus
• Other Moving Parts

7. General Safety Principles
• Do not leave machines running and
unattended
• Never attend to brush debris from the table
surface while the machine is running
• An active brake mechanism adds greatly to
safety
• Easily reached “off” switch increases safety
• Always wear appropriate safety gears

8. Incident HistoryIncident History
• Incidents occurred due to:
• Lack of protection (e.g. equipment
safeguards);
• Not following procedures;
• Lack of training;
• Lack of maintenance;
• Horseplay; and
• Others

9. • These incidents can cause
• Damage to the body, e.g. cuts, crushing of
limb, etc
• Injuries by energies released from the
machine, e.g. electrical shock, burn, etc
• Fatalities
