What precaution should be taken to manage potential hazards from pressure sources?

To manage potential hazards from pressure sources effectively, isolating or tagging out the pressure sources is a critical precaution. This step helps ensure that the equipment is rendered inoperable and cannot be accidentally pressurized while maintenance or inspections are being conducted. By isolating the pressure source, you minimize the risk of sudden release or failure, which can result in serious injuries or accidents.

Tagging out is a part of this process and typically involves placing a tag on the equipment that communicates to others that it should not be operated. This practice is essential in environments where multiple personnel might be working, as it informs everyone of the status of the equipment and promotes a safer work environment.

Other practices may provide some level of safety, such as wearing protective gear, but they do not address the root hazard associated with working on live pressure systems. Similarly, only working during daylight may improve visibility but does not mitigate the danger posed by high-pressure systems. Using hoses longer than necessary might introduce unnecessary risks in terms of kinks or damage, which can compromise their integrity.

Thus, isolating or tagging out pressure sources is the most effective and preventive measure to control potential hazards, ensuring a safer working atmosphere for all involved.
