Modified blowguns were highlighted as a source of multiple risks in world-leading manufacturing facility.

 

Health and Safety inspection reduces risk and realises hidden benefits

When experienced Quality, Environment, Health and Safety Manager Andrea O'Connor took up her new role as QSHE Manager at Prior Scientific, she wanted to quickly act to identify any possible exposure to risk. This revealed an issue with the use of blowguns across various manufacturing operations. In an engineering context, blowguns serve several functions that contribute to maintenance, cleaning, and overall operational efficiency. However, training and adherence to safety guidelines are essential when using blowguns, as the compressed air can potentially cause harm if not handled correctly. Andrea identified several potential risks when observing operations.

 

Cambs Compressors were approached to help resolve the issues identified

The issues identified were commonly experienced and were a result of the lack of understanding the dangers at an operational level. However, it was also discovered that the blowguns had been adapted and modified by their users to aid the processes being performed. Cambs Compressors experimented to create a specific configuration for the issues identified. They provided a custom built blowgun prototype, using a range of standard components, to address the user frustrations as well as the risks to health and safety.

 

The new custom built blowguns delivered the following benefits:

• Reduced noise by 15DB
• Minimised recoil in use
• A deflector stopped spray back
• A regulator ensured pressure reaching the blowgun is a safe and manageable level
• The blowgun was lighter

 

The hidden benefits were

• Modified guns leaked, replacing them boosted the systems compressed air capacity
• Standardised blowguns across the manufacturing site rationalised spares
• Safety induction was standardised as all blowguns were the same

 

The most common blowgun risks identified in an engineering application

Compressed Air Hazards: The high pressure of compressed air used in blowguns can cause serious injuries if directed at the body, especially sensitive areas like the eyes, skin, or ears. Air pressure exceeding safe levels can lead to physical harm, including tissue damage or hearing impairment.

Flying Debris and Particles: When blowing air to clean or remove debris, particles can become airborne and pose risks to nearby personnel. These particles can cause eye injuries, respiratory issues, or skin irritation if inhaled or come into contact with the skin.

Projectile Danger: If small objects or loose materials are present in the area, the force of the compressed air can turn them into projectiles, creating a risk of injury to employees or damage to equipment.

Static Electricity: The discharge of static electricity can occur when using blowguns, especially in certain environments or with specific materials. This can lead to potential ignition in areas with flammable substances or explosive atmospheres.

Hearing Damage: The loud noise generated by the air escaping from the blowgun can contribute to hearing damage over time if proper hearing protection is not used.

Ergonomic Strain: Holding a blowgun for extended periods or in awkward positions can lead to ergonomic strain and discomfort, potentially resulting in repetitive strain injuries (RSIs) or musculoskeletal disorders.

Lack of Proper Training: Inadequate training on the correct use of blowguns, including safe handling procedures and proper distances, can lead to accidents and injuries.

Pressure Regulation: Using excessively high pressure levels in blowguns can lead to unintentional damage to sensitive equipment, delicate components, or surfaces.

Inadequate Personal Protective Equipment (PPE): Failing to provide or use appropriate personal protective equipment, such as safety glasses, gloves, or hearing protection, can increase the risk of injury.

Improper Cleaning Methods: Incorrect use of blowguns, such as directing air into tight spaces or sensitive equipment, can result in unintended damage or malfunction.

 

To mitigate these risks, engineering companies should take the following measures:

Provide Proper Training: Ensure that employees using blowguns are trained on their safe operation, potential hazards, and proper techniques.

Use Adequate PPE: Require employees to wear appropriate personal protective equipment to shield against potential hazards.

Set Safe Pressure Levels: Implement pressure regulators to control the air pressure from the blowgun and prevent excessive force.

Implement Safety Guidelines: Establish and communicate clear guidelines for using blowguns safely, including maintaining a safe distance and avoiding direct contact with the body.

Regular Maintenance and Inspection: Regularly inspect blowguns and associated equipment for damage, wear, or malfunction, and perform maintenance as needed.

By addressing these risks and implementing proper safety measures, engineering companies can maximise the benefits of using blowguns while safeguarding the wellbeing of their employees and equipment.
