Lesson contents • 1.1 – Safety Awareness • 1.2 – Personal Conduct & Shop Etiquette • 1.3 – Appropriate Shop Clothing • 1.4 – General Safety Practices • 1.5 – Tools, Machines, and CNC Safety Practices • 1.6 – Shop Contract

Objectives • Display awareness of shop safety. • Apply general safety rules. • Select appropriate shop clothing. • Demonstrate safe personal conduct in shop. • Apply additional precautions when using power tools, machines or running a new CNC program.

Think

Common hazards • Cutting tools are very sharp.

• Can cut if improperly handled.

• • • • • •

Spinning tools are extremely dangerous. Tools can shatter. Chips produced by machining are sharp. Machining throws off hot, sharp chips at high speed. Welding arcs can damage eyes – use a welding helmet. Prevent burns by wearing leather gloves and protective clothing when welding or working with hot metals.

Think Safety

Common Causes of injuries • Flying chip => eye injury. Look For • Chips on bench => cut hand. Danger • Chips on floor => cut foot. • Not looking where your hands are moving. • Distraction – Inattention. • Using equipment without proper training. • Long hair catching in rotating machinery. • Slips, trips, and falls. • Touching hot tool or workpiece

Preventing injury • Know where your hands are at all times. • Look before you move. • Move deliberately - cautiously. • Always ask yourself, “What happens if…” • Tool slips? • Hand slips? • Feet slip?

Be Aware

Be Serious

Shop etiquette • Never borrow tools without first asking. • Respect the professional machinists and shop monitors. • Don’t make unreasonable demands (“I need it yesterday”, etc.) – PLAN AHEAD! • Clean up after yourself. • Best Practice: Leave workspace at least as clean as you found it.

• Put away all tools. • Wipe clean first. • Put where/how found.

General safety practices • Wear safety glasses at all times in shop. • Not just at CNC or other machines.

• Know how to use Emergency Stop. • Never work alone. • Only 1 person in charge of machine at a time. • Never use hands or air hose to clear chips. • Best practice: Use a paint brush instead.

General Safety practices • Clean spills immediately. • Store oily rags in fireproof can. • Oily rags can spontaneously combust .

• Lift with legs, not back. • Do not lift heavy objects alone. • Get help or use a lift.

1.5 – Power tool and CNC Safety practices • Never leave CNC machine or other equipment running unattended. • End program with part nearest operator. • So you don’t have to lean far into machine to load/unload part.

• Remove tools from spindle at end of day. • Remember that the working edge of tools is very sharp. • Remember that both chips and workpieces may be very hot just after a cutting, shaping or welding operation • Avoid contact with coolant. • Be conscious of the location of cords when using portable power tools. Cutting through a cord can result in electrocution. • Immediately wash and treat cuts. Eyewash station is available for flushing irritants or chemicals from eyes. • Report all injuries.

“First article” safety for CNC Machines • Use machine rapid and feed override. • Ensure Tool Length Offsets (TLO) are correct. • Ensure Fixture Offsets are correct. • Use Extra caution at starts & tool changes. • Keep hand near E-Stop. • Stop machine at first sign of trouble.

Hazardous Substances • Information about the composition and hazards of certain substances used in the shops and labs is available in each location • Material Safety Data Sheets or MSDS binders are posted at an accessible point
