In refrigeration and HVAC, it's out with old, complex systems and in with new, efficient ammonia systems. When working with low-charge ammonia systems, managers need to follow a safety management process that includes ongoing training.
For manufacturers, suppliers, and end-users in refrigeration and HVAC, low-charge anhydrous ammonia is all the rage. Using the tiniest quantities of this economical gas, newer compact systems improve efficiency and provide cost savings.
Another benefit of using low-charge ammonia refrigeration systems is that it is much safer for workers. However, continuous risk assessments, emergency plans, and communication are still key to compliant, efficient, and safe ammonia management.
According to the Centers for Disease Control and Prevention, anhydrous ammonia is among the top five chemicals causing injuries in acute incidents. The top two causes of the ammonia release accidents were equipment failure and human error.
Recently, a worker was severely burned in an anhydrous ammonia incident at a beef processing plant in Nebraska. The company incurred 16 OSHA violations, including failure to comply with lockout/tagout rules and not following process safety management.
"When employers fail to properly document procedures and control highly hazardous chemicals, there is the potential for unintentional releases that can result in serious and fatal injuries," said Omaha Area Director Jeff Funke. "By implementing and sustaining workplace safety and health programs, employers can monitor their processes to ensure safeguards are in place to protect workers."
Before any work, employees should understand OSHA compliance for hazardous chemicals and basic ammonia fundamentals.
Complying with OSHA�s Process Safety Management
The Occupational Safety and Health Administration (OSHA) has guidelines in place to prevent serious accidents with hazardous chemicals like ammonia. These practices are called OSHA�s Process Safety Management (PSM) standard.
Here's a simplified breakdown of key parts of PSM:
1. Communicate Clearly
Increasing safety awareness is all about influencing behavior. Safety managers can reinforce conversations on work on or around low-charge ammonia stations by using reminders that catch the eye of an employee or even a visiting contractor. For example:
2. Follow Through on Risk Management
Safety risk management starts with a job hazard analysis. This step is necessary when anhydrous ammonia is in use, according to OSHA. A hazard analysis not only identifies potential danger, but it also helps assess compliance. For example:
3. Continuous Training
Having lax procedures when working with ammonia can injure workers and put surrounding communities in danger. Using communication, a solid risk management plan, and continuous training, facility safety managers will enhance productivity and reduce operational costs. When planning risk assessment inspections in 2019, focus on contractors conducting installations, maintenance, and other activities on ammonia systems. By posting instructions and other messages, refrigeration maintenance workers are more likely to pay attention.
