Clemco's CMS-4 Carbon Monoxide Monitor-Alarm will replace the CMS-3, which is no longer in production. It is practically identical in operation and appearance to the CMS-3; however, the CMS-4 has improved electronics for monitoring levels of carbon monoxide. Don’t worry: even with the updated electronics, the CMS-4 is at the same price point as the CMS-3.
The CMS-4 is an in-helmet CO (Carbon Monoxide) monitor that alerts users when CO exceeds 10ppm—the US limit set to meet Grade D quality breathing air requirements. When the monitor detects dangerous levels of CO, a warning light and a high-decibel audible alarm will be set off.
Air supply can be compromised while using a diesel-powered air compressor. The breakdown of oil lubricants in the compressor or contamination from diesel exhaust can expose you to the danger that is CO poisoning. This is what makes carbon monoxide monitors so important to blast operations.
There’s a reason why carbon monoxide is known as the “silent killer.” CO is colorless, odorless, and non-irritating. Without a proper CO monitor/alarm, you could be unknowingly exposing yourself to a potential life-threatening gas. Safety should be at the forefront of any sandblasting operation. You can learn more about the dangers of carbon monoxide poisoning here.
The CMS-4 is an in-helmet monitor as a package or monitor-only option. For a field-portable CO monitor/alarm that does not fit inside the helmet, we still carry the Clemco CMS-2 with a rugged polyethylene carrying case.
Note: calibration cups used with the CMS-3 monitor will not fit over the CMS-4’s sensor retainer. If you have any questions, do not hesitate to reach out to our customer service team.
A remote control system is an OSHA-required safety device. The control handle, often referred to as a dead man switch, is the trigger for the RC system. When the operator releases the RC handle, the machine deactivates, stopping air and abrasive flow through the nozzle. The remote control system “fails to safe,” which means that with any interruption in [...]
More and more blasting contractors are making the switch to low-pressure respirators. A high-pressure respirator requires an air source of 6 to 15 cfm at 65 to 100 psi. Some contractors connect their high-pressure respirator to the same compressor that supplies the blast air. A low-pressure respirator requires just 8 to 15 psi, but still [...]
Low Pressure or High Pressure, Choose Respirator Based on Quality of Air Supply Health and safety regulators are taking a closer look at how blast operators use their high-pressure respirators, long the main-stay of the blasting industry the world over. Their primary concern – what is in the air supplied to the helmet?High-pressure respirators [...]
How many of us really read the owner's manual that accompanies our new purchase? Every Clemco owner's manual contains important information about the safe and efficient use of our equipment. Doing your homework and selecting the right equipment and media for your blast application are only the first steps to achieving an efficient operation.Blast equipment, [...]
As the days get longer and the weather gets warmer, summer is within our grasps. While you might enjoy the sunny days, your blast machine might not. Warmer weather means increased humidity in the air. This causes the warm air produced from your air compressor to condense allowing moisture to enter your blast pot. As a result, the abrasive [...]
Abrasive media valves are used to regulate the flow of abrasive from the blast pot on a sandblasting machine. Just like choosing the right blast nozzle and blast hose, you want to make sure you choose the right type of media valve for your machine and abrasive of choice.When it comes to metering valves, there are two types: [...]
