Reducing Sanding-Related Risks

What can you do to sand safer?

Sanding comes with some downsides, but there’s a lot you can do to sand safer.

Dust From Sanding Silica

Eliminating

As long as silica-containing materials are the best and most economic materials in the sectors that utilise them, elimination of the dust hazard will consist of reducing the necessity for on-site sanding (and cutting and drilling) of the products. Dust generation will not be fully eliminated but will be confined to the production environment where safety is more tightly controlled.

Reducing

In a factory or workshop environment, the best strategy is to use engineering controls like enclosures or hoods and local exhaust ventilation to extract the contaminated air, or to use water suppression. When working with hand-held power tools the best strategies are to use localised ventilation on the tool or suppress the dust using water spray systems.

Dust From Sanding Wood

Eliminating

Similarly, as long as there is a demand for wood products, the best way to eliminate the on-site dust hazard for workers will be to design solutions using pre-finished elements.

Reducing

On-tool extraction is the best control for dust from sanding, as local exhaust ventilation deals with the problem at its source.

Dust From Sanding Gypsum

Eliminating

Employers in the UK are required to consider alternatives to avoid the need for sanding. EuroGypsum and the European Union of Plasterers (UEEP) promote “Surface Quality Level 4” as the desired standard for plasterboard finishing. This level of finish improves working conditions because sanding is not required, and it introduces spray plaster skimming machines to the process, the use of which will reduce the risk of musculoskeletal disorders. 

Reducing

If plasterboard joints need to be sanded, then the use of appropriate on-tool extraction will reduce the amount of dust in the air. 

Dust From Vehicle Body Repair

Reducing

It is difficult to eliminate dust from sanding in vehicle body repair. But it is possible to reduce the amount. In the controlled environment of a vehicle repair workshop, a combination of personal protective equipment, on-tool extraction, and separation of sanding activities from other activities will reduce the risks related to sanding.

Hand-Arm Vibration

If the job can be done practically without vibrating tools, it should be done without them. It is the responsibility of the employer to reduce the risks from vibration to as low as is reasonably practicable.

If vibration exceeds the exposure action value (2.5 m/s2 ), the employer is legally required to act to reduce the exposure. The employer must not allow exposures to exceed the exposure limit value (5 m/s2 ). Hand-arm vibration meters worn by the user are the most accurate way of determining the level of vibration experienced when a tool is being used and measuring the cumulative exposure to that vibration.

 

Checklist When Machine Sanding

If a job has to be done with vibrating tools, HSE (UK) recommends that workers take the following measures:

  • Ask to use suitable low-vibration tools.
  • Always use the right tool for each job (to do the job more quickly and expose you to less hand-arm vibration).
  • Check tools before using them to make sure they have been properly maintained and repaired to avoid increased vibration caused by faults or general wear.
  • Reduce the amount of time you use a tool in one go, by doing other jobs in between.
  • Avoid gripping or forcing a tool or workpiece more than you have to.
  • Store tools so that they do not have very cold handles when next used.
  • Encourage good blood circulation by keeping warm and dry (when necessary, wear gloves, a hat, waterproofs and use heating pads if available)
  • Giving up or cutting down on smoking because smoking reduces blood flow;
  • Massaging and exercising your fingers during work breaks.

Noise

The European Directive requires that risks arising from noise exposure be eliminated or reduced to a minimum. Examples of risk reduction are to decrease the exposure to noise, training workers in the correct use of equipment, installing shields, and, noise-absorbing material.

After such practicable means of eliminating or reducing the risks have been implemented, the workers need to be provided with hearing protectors that fit them properly and that are suited to their work.

Musculoskeletal Disorder Risk Factors

The assessment of repetitive tasks tool published by HSE (UK) gives a useful guide for identifying aspects of a task that could be aggravating factors in the development of an MSD.

The assessment is split into four stages:

  1. Frequency and repetition of movement,
  2. Force
  3. Awkward postures
  4. Other factors

If it is reasonably practicable to eliminate the risk factors, for example, by redesigning the job, automating a task, using different tools, or working at an adjusted height to avoid an awkward posture, then that is the first step that should be taken. 

If a task cannot be eliminated, then consideration should be given to how to reduce the risk factors. Could the task be shared between workers to reduce the frequency and duration of the task for the individuals? Is it possible to reduce the force used or the repetition required when performing the task?

What can be done in the organization?

Reducing negative psychosocial risk factors

Recognising that company culture cannot change overnight, the European Agency for Safety and Health at Work has identified the key elements of a potentially effective strategy for workplace interventions:

  • Commitment. There needs to be commitment at all levels to addressing both the physical risks of MSDs and the psychosocial risks.
  • “Holistic approach to risk assessment, covering both physical and psychosocial risks... The risk assessment process requires management commitment and should actively involve the workforce, and it should ensure that actual work activities are assessed, not what is believed to happen.”
  • An honest and open approach.
  • For risk prevention, evidence suggests that if risks are identified and solutions are developed in collaboration with the workforce, the process is more likely to be successful than if solutions are imposed by management. 
  • Ongoing review.
  • Rehabilitation, not just initial prevention.
