Hoses can create serious hazards on the job, including risks from high pressure, extreme temperatures, chemical exposure, and trip hazards.
Always use the correct type, length, and diameter of hose for the task. Use the proper hose safety devices including pins. Ensure all parts of the hose assembly, including clamps, fittings, valves, couplings, and safety devices, are properly installed and securely tightened. Use hose chafing guards when needed and replace any chafing guards that are damaged or missing.
Proper use, regular maintenance, inspections, and safe storage are essential to prevent leaks, early deterioration, and hose assembly failure all of which could lead to tragic consequences.
Wear appropriate PPE when working with hoses which may include a hardhat, safety glasses or goggles, gloves, and protective footwear.
Regularly inspect hoses and all parts of the hose assembly for signs of wear or damage. Replace hoses that show signs of cracking, blistering, or other deterioration. Do not used damaged hoses.
Housekeeping is an essential component of maintaining a safe work area when hoses are in use or being stored.
Hoses can often become a trip hazard, and all passageways and work areas should be kept clear. Hoses, cables, and other equipment should not be blocking walkways, ladders, and stairs.
Keep hoses stored properly, in clean and dry conditions, when not in use. Do not stack hoses.
If available, use hose reels or hangers to store hoses off the ground or away from the walkways. If the hose is hanging, make sure that no part of the hose is bending more than the manufacturer’s bend radius to prevent kinking.
Slick floors can be a significant hazard when using hoses. Keep work areas dry and clean to prevent slips and trips. Use hose guards or protective covers to minimize trip hazards and protect the hoses in walkways and work areas.
If hoses are frequently in use in the work area, mark those areas with signage, high-visibility tape, barricades, or other methods to alert workers to potential tripping hazards.
Hoses may be tough and durable, but they're not invincible—treat them right, or they could fail when pushed too far. Damage to hoses may include:
- Erosion – wear on the hose that can weaken it over time
- Abrasion – surface wear from friction against rough surfaces
- Failure – may be caused by improper assembly or use, prolonged stress, or exceeding limits
- Pinhole Leaks – tiny holes in the hose that are hard to detect and can be dangerous
- Bursts – sudden rupture typically from excessive pressure or severe structural weakness
Hose fatigue and hazardous environments can damage hoses resulting in injuries, or worse.
Hose fatigue refers to the wear and degradation that a hose experiences over time due to repeated use, pressure fluctuations, and environmental stressors. This can weaken the hose, increasing the likelihood of failure or rupture.
Exposing hoses to a hazardous environment accelerates wear and increases the risk of failure. When a hose is used or stored in conditions where it is exposed to harmful elements like extreme temperatures, hazardous chemicals, or abrasive substances, this will further compromise its integrity and performance.
High-pressure hoses can cause severe injuries if they rupture or are disconnected improperly. Ensure that all connections are secure and use correct clamps and fittings. Use the correct pressure-rated hoses and fittings to prevent accidental release. Always confirm that hoses are depressurized before disconnecting.
When working with or around pressurized hoses struck-by and pressure injection injuries are a risk that can result from:
- A connection failure or the improper fastening of a connection
- Disconnecting a pressurized hose
- Failure to use proper hose safety locks and restraints
- Exceeding the pressure capacity of hose
- Damaged hoses
The pressure rating of a hose assembly is determined by its weakest component. For example, a hose rated for 300 PSI won’t hold at that pressure if its coupling is only rated for 50 PSI. It’s essential to know the pressure rating of the entire assembly, not just the hose itself. Always stay within the specified pressure limits of your hose assembly.
High-temperature hoses require special care. They should be constructed from heat-resistant materials designed for high temperatures, and regularly inspected for signs of wear or damage. Avoid direct contact with these hoses to prevent burns or other injuries.
When using hoses that carry chemicals, workers should understand the associated hazards and review the Safety Data Sheets (SDS) beforehand to ensure safe handling and awareness of potential risks.
Purging is a critical safety step when working with hoses that may carry hazardous or pressurized materials. Before disconnecting, storing, or performing maintenance, ensure hoses are purged to remove residual contents. This process prevents accidental exposure to harmful chemicals, pressurized gases, or other potentially dangerous substances that could remain inside. Use appropriate purging techniques and follow safety guidelines to minimize risks of exposure, spills, or pressure release.
Cleaning hoses regularly can prevent buildup of materials that can cause blockages or increase wear. Follow the manufacturer's recommendations for cleaning methods and solutions. Proper cleaning extends the life of hoses and maintains their safety.
