Confined spaces such as sewers, pipes, access shafts, tanks, and utility vaults can be hazardous due to the presence of flammable gases and other potentially toxic substances. Workers who are exposed to these conditions lose consciousness or sustain severe injuries such as burns.
Safety is non-negotiable in the industries served by Hetek Solutions, which includes gas and water utilities, municipalities, and the midstream and upstream oil and gas sectors. It is vital to choose the best portable gas detector, also called a personal gas monitor by the Canadian Centre for Occupational Health and Safety (CCOHS), to protect your employees. Use this buyer’s guide to select portable gas monitors for your team.
The Role of Personal Gas Monitors
Personal gas monitors are essential personal protective equipment (PPE). Some industries require employees to wear them full-time, while others instruct workers to attach the monitor only when they enter or work in confined spaces. The devices are designed to assess atmospheric conditions surrounding individual workers and immediately alert them to potential hazards. Users can set the portable gas detector to monitor one specific gas or multiple gases simultaneously.
Portable gas detectors have visual and acoustic alarms that trigger when gas concentrations exceed pre-programmed alarm thresholds. It allows teams to leave the work area immediately and initiate safety measures. Hetek’s personal gas monitor range includes devices with an internal pump, enabling users to perform a pre-entry check to ensure the area is safe before entering.
How to Use Gas Monitors Effectively
Always follow manufacturer guidelines and company safe work practices when using a personal gas monitor. Do the following to be safe and monitor gas usage correctly.
- Select the correct portable gas detector for the task.
- Bump test the instrument on the docking station.
- Check the battery.
- Zero the instrument in fresh air to establish a baseline reading.
- Clear the peak readings.
- Understand what each alarm means and how to respond to an alarm event.
- Wear it at the correct position, as close as possible to your nose and mouth, on the outermost garment. Keep it uncovered at all times.
- Appoint professionals to calibrate and service the instrument per guidelines.
Understanding the Different Types of Gas Detectors
Each industry has specified requirements for portable gas monitors used in confined spaces and other environments. The best portable gas detector is a device that monitors the gases prevalent in each working environment, whether that is a single gas such as carbon dioxide (CO2) or multiple gases. Hetek has different types of personal gas detectors that individuals and teams can wear as PPE.
PS200 Portable 4-Gas Monitor
The PS200 measures any combination of lower explosive limit (LEL), oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S) gases. It has an optional internal pump. A multifunctional PS200 – Auto Bump & Calibration (ABC) station provides simple but intelligent testing and calibration.
ToxiRAE Pro CO2 Monitor
The ToxiRAE Pro CO2 is a wireless personal monitor equipped with a “Man Down” alarm and remote access to real-time instrument readings and alarm status.
The MiniRAE Lite + VOC Monitor
The MiniRAE Lite + is a handheld volatile organic compound (VOC) monitor ideal for leak detection, environmental cleanup, and remediation environments.
Why Gas Detector Maintenance Matters
Gas detection system maintenance is a matter of life and death. The best portable gas detector is ineffective if the instrument is not correctly calibrated. Regular calibration, performed by professionals, ensures the instrument provides accurate gas concentration readings that prevent worker illness, injury, or death.
Calibration certificates must be provided after each service to ensure a company’s personal gas detection instruments are compliant with regulations and health and safety guidelines. Hetek’s manufacturer-trained technicians are experts in the repair, service, and calibration of portable gas monitors. We service and calibrate equipment at our labs or at customer locations via our mobile service.
