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
Produce fine dust Electrical Hazards Noise Health Hazards

Tale Practices for Tool Safeguarding and Controls
Oscillating Spindle Sander
Drill Press Safety Hazards Sharp cutting bit – minor lacerations, punctures Clutter with chips and scraps Rotating chuck and bit –entanglement Flying objects – from parts working or centrifugal throw (chuck key, part) – eye, face,
skin injuries Torque exerted on work piece – impact Electrical 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

Cold Saw
Metal Chop Saw High speed rotating cutting wheels and shafts-lacerations, amputations Flying objects- eye, face, skin injuries Pinch point hazards Heat/sparks- burns, fire Dust exposure Noise exposure
Reference: Yale Environmental Health & Safetyhttp://ehs.yale.edu/sites/default/files/files/metal-chop-saw.pdf
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
Water Jet Noise, hearing hazard Cutting:
High-speed jet laden with abrasives Sharp jagged slats in the machine tank
Abrasive-related hazard: Water splash back from the machine: wear safety glasses Disconnecting pneumatic lines can cause abrasive particles enter eyes
Pressure-related hazards Compressed water Metal fatigue
Electric hazards High-power rotating parts Pinch point Use overhead crane with vacuum or magnetic lift device
Finger Brake Cut hazard – finger crushing Pinching hazard- entanglement Sharp edges and burrs Impact from counterweight
Metal Brake
Magnetic Brake Crush hazard Keep clear of moving object (clamp handle and the counterweight are heavy, can swing
back) Electrical and magnetic fluid High voltage
Roll Bender Caught between / pinch points – crushing, amputation Contact with sharp edges of metal sheets Impact from handles or bending beam Electrical hazards
Tube Bender
3. CNC Router & Laser Cutter
5 Axis CNC Router Safety Hazards
Sharp cutting tool – lacerations, amputation Rotating tool –entanglement Flying objects – eye, face, skin injuries
Electrical Hazards Noise Fire and Explosions Hazards
Sawdust or other material dust Flammable materials such as paints, oil finishes, solvent, etc.
Health Hazards Wood/foam dust
Dermatitis Allergic respiratory effects Cancer
4 Axis and 3 Axis CNC Router
Laser Cutter Station Laser – ocular injury, burns Fire hazard burns, fire‐ Laser generated air contaminants
