Machine Hazards

1. Wood Working

Machine Name Potential Hazards and InjuriesRouter Table Safety Hazards

Rotating/sharp cutting blade- serious lacerations or amputation In-running Nip Points -clothing, hair, or hands may be caught by and pulled into the

in-running rolls) Point of operation-Contact with the moving blade may occur. Kickbacks- stock caught in the blade or fed in the wrong direction may be thrown

back at the operator. Flying chips: workpiece, wood chips and splinters may be thrown by the cutting

action- eye, face, skin injuries Tool projection

Electrical Hazards Noise Fire and Explosions Hazards

Sawdust Flammable materials such as paints, oil finishes, solvent, etc.

Health Hazards wood dust

Dermatitis Allergic respiratory effects Cancer

Vibration hand-arm vibration syndrome (HAVS)

Finishing Chemicals

Band Saw

Saw Stop Table Saw

Panel Saw

Miter Saw

Combination Belt Sander & disk Sander Safety Hazards Pinch point: contact with disc or belt may occur- crushing, bruising Rotating pulleys, belts entanglement‐ In-running nip points—Clothing, hands, or hair may get caught by and pulled into the

in-running rolls on automatic sanders or sanding belts. Flying chips: Wood splinters and chips may be thrown from the sanding action- eye,

face, skin injuries Fire and Explosions Hazards

2. Metal Working & Hot Zone

Tig and Mig Welders Asphyxiation: Compressed gas, including inert gas Eye injuries: caused by exposure to ultraviolet and infrared radiation created from the

arc Noise Electrical hazards Heat/burns Fire hazards Health Hazards

Welding fumes and gases: eye, nose and throat irritation, dizziness and nausea; prolonged exposure can cause lung diseases; metal fume fever; kidney

Metal Drill Press Sharp cutting bit – minor lacerations, punctures Rotating chuck and bit- entanglement Caught between- crushing Flying objects-from parts working or centrifugal throw (chuck key, part)- eye, face, skin

injuries Higher torque on work piece – impact injuries noise

Reference: Yale Practices for Tool Safeguarding and Control

Hydraulic Press Caught between- crushing Flying objects – eye, face, skin injuries

Metal Band Saw Cutting blade – lacerations, amputation Rotating blade pulleys – pinch points, entanglement Flying objects – eye, face, skin injuries noise

CNC Plasma and Water Table (Plasma Cutter)

Noise Plasma-ocular injury, burns Heat- burns, fire

Finger Brake Cut hazard – finger crushing Pinching hazard- entanglement Sharp edges and burrs Impact from counterweight

Metal Brake

Roll Bender Caught between / pinch points – crushing, amputation Contact with sharp edges of metal sheets Impact from handles or bending beam Electrical hazards
