Grade 10 metalwork – Safety in the Workshop Quiz

A bench grinder throws sparks and small metal fragments; safety goggles or a face shield protect your eyes and face from flying debris and reduce risk of serious eye injury.

Water spreads oil fires and makes them worse. For flammable liquids, a dry chemical or foam extinguisher is appropriate to smother the flames safely.

Secure clamping and correct tool rest position prevent the workpiece from flying out or the tool from catching, reducing the risk of injury and accidents.

Using the legs keeps the back stable and reduces strain on the spine; bending at the waist or twisting increases risk of back injury.

A 'Keep Clear / Safe Distance' sign warns students to stand away from machines while they are operating, reducing risk from moving parts and flying debris.

Loose items can become entangled in rotating parts, pulling the person into the machine. Securing them prevents entanglement and serious accidents.

Damaged cords can cause electric shock or fire. Stopping use and replacing or reporting ensures safety for everyone in the workshop.

Prompt cleanup reduces slip hazards, prevents fires, and lowers the chance of cuts or puncture injuries from sharp shavings.

High noise can damage hearing over time. If you cannot hear someone speaking at a normal voice nearby, ear protection should be used to prevent hearing loss.

Carrying sharp tools pointing down and close reduces the risk of stabbing yourself or others; tool holders add extra protection during transport.

Metal filings are sharp and can cut hands. Using a brush or magnet removes them safely without risking injury.

Proper instruction and supervision ensure you know safe methods and settings before using a machine, preventing accidents caused by misuse.

Correct tools fit the task, reducing the need for force or awkward positions that can cause slips, breaks, or injuries while improving workmanship.

Oily rags can spontaneously combust; a sealed metal bin prevents oxygen contact and reduces fire risk compared with ordinary trash containers.

Prompt reporting ensures the injured person receives care and helps prevent further incidents by addressing hazards and following school safety procedures.

Many fluids and paints release vapours that can be harmful if inhaled; proper ventilation reduces exposure and protects respiratory health.

Lockout/tagout ensures the machine cannot be accidentally turned on while being serviced, protecting workers from unexpected start-up hazards.

Quick, orderly evacuation using marked routes and assembly points ensures everyone's safety and allows teachers to account for all students.

Proper storage with guards or racks prevents accidental contact with sharp edges and keeps the workplace organized and safe.

Machine guards provide a physical barrier between people and hazardous moving parts, significantly lowering the chance of entanglement or crushing injuries.

Stopping the machine prevents sudden movement that can cause severe injury; investigating while it runs is dangerous and can lead to entanglement.

Inspecting tools helps identify cracks, dullness, or loose parts that could fail and cause accidents during use.

Assuming metal is hot and using proper tools prevents burns; marking hot items warns others and reduces accidental contact.

Tinnitus or ear pain can indicate hearing damage. Reporting allows for assessment and prevents further harm by reducing exposure.

Proper labeled and sealed storage in a ventilated area prevents spills, reduces vapour buildup, and lowers the chance of fire or poisoning.

Smelling gas or strong fumes could indicate a leak or hazardous release. Reporting and evacuating protect everyone and allow trained staff to handle the hazard safely.

Safety goggles with side protection prevent metal sparks and fragments from entering the eyes. Regular glasses or a cap do not give full protection, and a paper dust mask does not protect the eyes.

Using lockout/tagout ensures the machine cannot be started accidentally while being repaired, protecting you and others. Leaving it running or unsafe isolation risks severe injury.

Bending the knees and lifting with the legs keeps the back straight and uses stronger leg muscles, reducing the chance of back strain. Twisting or bending at the waist increases injury risk.

CO2 extinguishers remove oxygen and are non-conductive, making them suitable for electrical fires. Water conducts electricity and is dangerous on electrical fires; wet chemical is for cooking oil fires.

Cylinders must be stored upright and secured to prevent falling, separated by gas type and kept away from heat sources to avoid leaks, fires or explosions.

Cooling with running water reduces heat and tissue damage. Putting oil or butter or breaking blisters can cause infection and worsen the injury.

Jewellery can snag on rotating or moving parts and cause serious injuries like crushing or amputation. Cleanliness is not the main safety reason.

Exposed wires are an electrocution and fire hazard. The correct action is to stop using the device, report it, and ensure it is repaired by a qualified person.

Clamping prevents the workpiece from moving, giving better control and preventing injury. Holding by hand or asking someone to hold is unsafe.

Welding produces harmful fumes and gases that can damage the respiratory system; ventilation or extraction reduces exposure. Comfort or brightness are not the main safety issue.

Safety boots protect feet from falling heavy objects and sharp metal. Sandals or thin shoes offer no protection and are unsafe in a metalwork environment.

Removing flammables and following permit procedures reduces the risk of accidental fires. A bucket of water is not sufficient for all fires, and the other options do not address fire risk.

Stop, drop, and roll or smothering with a fire blanket removes oxygen and extinguishes clothing fires safely. Running fans flames and throwing water may spread some fires; removing clothing can cause more injury.

A clean floor reduces the risk of falls and injuries from sharp offcuts. Neatness or inspection is secondary to safety.

Using both hands, correct disc type and guard reduces kickback and shards hitting you. Worn discs or removing guards increase risk of broken discs and serious injury.

MSDS (or SDS) gives essential safety information about chemicals so users can handle them safely and respond correctly in emergencies. It is not a contact list or instructions for making chemicals.

Proper ear defenders or rated ear plugs reduce noise exposure and prevent long-term hearing loss. Cotton balls or ignoring the noise are ineffective.

Compressed air can drive debris into the skin or eyes and cause serious harm. Although it is noisy, the main hazard is physical injury from particles.

Respirators and extraction systems reduce inhalation of harmful dust and fumes. Holding your breath or working faster does not protect you; outdoor work may not be possible or sufficient.

Damaged tools are unsafe; tagging them out prevents use until repaired or replaced. Using defective tools risks accidents.

Clamping the work and using correct technique prevents slipping, improves control and reduces injury. Loose holding or incorrect blades is unsafe.

Clear exits ensure everyone can leave quickly in a fire or other emergency. Storing items there would block escape and increase danger.

Young students must be trained and supervised to ensure safe operation. Unsupervised or insufficiently trained operation is dangerous.

Turning off gas safely, ventilating, evacuating and notifying staff reduces risk of fire or explosion. Lighting a match is extremely dangerous.

Helping should be limited to those trained and following instructor guidance to avoid accidents. Untrained assistance or unsafe holding increases risk.

Safe storage prevents accidental cuts and keeps tools in good condition. Loose or improper storage creates hazards.

Machine guards are a primary safety device to intercept fragments and stop fingers from touching moving parts. They are essential for all users.
