Powerful tips for tool safety

Whether at home or work, we all love getting our hands on big, grunty power tools. They make jobs so much easier and faster, but they do come with some risks 

Before you start on a job using power tools, stop and think about the work area, the tool itself and the operator. It will make you and your colleagues much safer on the job.

The work area

Hazards around you:

• If you are creating sparks, have you removed all flammable items?
• Is there any traffic in, or near, the work area?
• Are there power sources in the area?
• If you are cutting into floors, walls, or ceilings – have you identified any conduits?

If it’s a home project, pay particular attention to children. You should also consider any pets or animals in the vicinity.

The materials you’re working on should be secure, so that both your hands are free. It should also be off the ground, to provide the most comfortable operating position. Consider using a work bench and vice, sawhorses or clamps.

The power tool

Make sure the tool is in good condition and not damaged. You should pay particular attention to guards, dead man switches and electrical leads. Check the leads for cuts, wear, heat damage, or exposed wires.

It’s recommended that when purchasing tools, you buy known brands from reputable suppliers, such as PlaceMakers – they’re more likely to have all the necessary safety features and last longer. For commercial use, the minimum of IP33 standard applies – remember that domestic tools are for home use only.

Residual current devices

Use your power tool in conjunction with a residual current device (RCD). This is mandatory in the workplace and is highly recommended for around the house.

Modern homes and workplaces will have RCDs built into the electrical system; however, older buildings may not. You can purchase RCDs at a relatively low cost. Consider purchasing an RCD that meets or exceeds IP33 standards, also consider purchasing power tools that meet or exceed AS/NZ standards.

Tag, you’re safe

Additionally for workplaces, electrical leads and appliances are required to be periodically tested and tagged by a qualified person. The period varies depending on the workplace:

• Three months for building and construction.
• Six months for workshops.

The tool must, at a minimum, meet IP33 standard. This refers to protection from water and identifies the power tool as commercial and fit to operate on construction sites.

Ensure power tools are well maintained and that blades are kept sharp. Sharp tools are easier to use, produce better quality work and are less likely to jam or kick back. Make sure the tool is fit for purpose and, if a less dangerous tool can be used to complete the same task, use it.

Wear protection

All power tools create harmful levels of noise, particularly if used for extended periods. The usual control method is to wear hearing protection – either earplugs or earmuffs. Don’t be tempted to go cheap on hearing protection. Go for items that have been classified to a known manufacturing standard such as AS/NZS 1270.

Hearing damage starts at about the same level as an idling bulldozer, which is 85 decibels. If you have to significantly raise your voice to speak to a person within about one metre from where you’re standing, then it’s too loud, and you are already damaging your hearing.

Power tools can also create flying debris, which could damage your eyes. Wearing a rated pair of wraparound, close-fitting safety glasses will generally be sufficient in most situations. Where you’re using angle grinders or similar tools, you will need a full face shield – if a grinding wheel disintegrates during operation, a pair of safety glasses will not provide protection to your face (the important standard here is AS/NZS 1336).

Breathe easy

Activities such as sanding, sawing and grinding will create dust, so make sure you’re wearing a quality dust mask. A P1 or P2 class mask will take care of dust particles; if you need to protect against fumes, you will need a respirator fitted with an appropriate cartridge. All respirators should adhere to a known standard, such as AS/NZS 1716.

It’s good practice to place carbon filters in a sealed bag when not in use.

To prevent injuries from other accidents that may happen, ensure you are wearing the appropriate safety gear. Consider gloves, safety boots, a hard hat, chaps and anything else that is required.

A few minutes taken before you start will mean the job is done faster, safer and to a higher standard. Don’t forget our advisors are always available to answer any questions you have. Site Safe has a free ‘Ask an Advisor’ tool on the website.
