Who is this for

The Leak Testing Do Not Open Tag is used by maintenance engineers, inspection technicians, and safety officers to mark valves, flanges, and access points on pipework or vessel systems that are currently under pressure test or leak test and must not be opened during the test period. Opening a valve or joint while a system is under pressure test creates a serious risk of sudden pressure release, fluid ejection, and injury, and the tag provides an unambiguous instruction at the point of the hazard that prevents workers from inadvertently opening the connection while the test is in progress. It is used across oil and gas, chemical processing, mining, plumbing, fire protection, and any industrial facility where pressure testing of pipework, vessels, and systems is part of the commissioning, maintenance, or inspection process.

Frequently asked questions
How many tags come in a pack?

All of our tearproof tag packs contain 100 tags, making them practical for stocking site offices, tool rooms, and maintenance facilities. Buying in packs keeps per unit costs down and ensures you have adequate supply on hand without needing to reorder frequently. For larger operations managing multiple sites or high tag turnover, trade accounts and bulk pricing are available — contact the team to discuss your requirements.
Do the tearproof tags come pre-strung?

Yes, our tearproof tags come pre-strung and ready to use straight out of the pack. This saves time on busy sites where tags need to be applied quickly during isolation or equipment inspection procedures. The stringing is suitable for attaching tags to valves, switches, equipment handles, and isolation points. If you need tags attached using a specific method for your site procedures, the metal eyelet also accepts wire, cable ties, or nylon rope as alternatives.
What size eyelet do the tearproof tags have?

Each tearproof tag comes fitted with an 8mm metal eyelet. The metal eyelet reinforces the attachment point and prevents the tag from tearing where it is hung, which is the most common failure point on cheaper tags. An 8mm eyelet is a practical size for most standard wire, cable ties, padlock hasps, and isolation points found on Australian worksites, making the tags compatible with the majority of lockout tagout and equipment isolation setups without any modification.
What material are the tearproof safety tags made from?

Our tearproof safety tags are made from polypropylene, a synthetic material that resists tearing, moisture, oils, chemicals, and UV exposure. Unlike card or paper tags which deteriorate quickly on site, polypropylene maintains its integrity in the conditions you find on Australian construction, mining, and industrial worksites — heat, dust, grease, and rough handling included. Each tag is printed with no fade inks to ensure critical safety information stays legible throughout the tag's service life.
What types of safety tags are available in the tearproof range?

Our tearproof range covers a wide variety of tag types to suit most Australian worksite requirements. Available titles include Danger Do Not Start, Danger Do Not Operate, Out of Service, Personal Danger, Do Not Energise, Caution Repair, Caution Information, Out of Service, Commissioning, Information, Warning Do Not Remove, Inspected Ready to Use, Quality Control, Accepted, Rejected, Inspection, Passed Inspection, Failed Inspection, Repair Order, Leak Inspection, Q.A Approved, Q.A Hold, Quarantine, Full Cylinder, and Empty Cylinder. All are made from polypropylene with a metal eyelet and come pre-strung in packs of 100.
