Confined spaces are one of the most dangerous types of industrial applications because of the lack of ventilation and pockets of gas can easily build-up.

Pre-entry checks associated with entering confined spaces, such as storage vessels call for pumped multi-gas portable detectors to detect oxygen deficiency levels as well as toxic and flammable gases within the area.

Following pre-entry checks, workers need to be protected upon entering confined spaces. In a life or death situation, you want the confidence in a reputable gas detection product that will detect and alarm to fulfil worker safety.

At a1-cbiss, we review our gas detectors to ensure that we provide reliable, highly responsive gas detection equipment to assess and monitor oxygen levels, flammability, and toxicity to keep workers safe during entry or routine maintenance and operations.

Regular maintenance and servicing of facilities & machinery is essential for companies if they are to maintain high levels of productivity.

Maintenance shutdowns are planned because it is a chance to carry out major maintenance tasks more cost-effectively.

With additional onsite personnel, extra gas detection equipment is needed because the inspection and cleaning work that is expected to be carried out needs to be done as quickly and as safely as possible.

As well as selling gas detection equipment, a1-cbiss are one of the few gas detection companies that can hire out additional gas detection equipment for the shutdown. Hiring equipment is a sensible and cost-effective approach for when gas detection equipment is only needed for a short period of time.

Continuous area monitoring protects people and property for airborne toxic or poisonous gases within a perimeter.

Continuous monitoring using a fleet of wireless area gas monitors minimise the risk preventing annoyance to the surrounding community.

a1-cbiss supply Oldham’s BM25 wireless area gas monitor as an ideal solution for boundary monitoring because they do not require wiring.

Wireless gas detectors provide remote, real-time monitoring and data collection, and data-logging for a permanent, time- and location-stamped, verifiable record.

Gas Leak Detection

Minimise the risk of exposure, explosion, or loss of product with a gas leak detection programme that ensures that all areas, pipes, valves, and pumps are regularly checked.

a1-cbiss can provide portable gas leak detectors, survey monitors, area gas monitors, and fixed gas detection systems for a comprehensive, real-time gas detection programme.


There are many dangers associated with the task of oil and gas exploration. Operations are safety-critical because of the location where exploration takes place. All workers are issued with personal gas detectors to protect them around the clock. Surrounding areas are also protected using fixed gas detection systems to assist in monitoring for high concentrations of toxic gases and VOCs.

With the flexibility of personal, portable, and fixed gas detection products and systems, a1-cbiss offer field-proven systems detect a variety of gases and provide around-the-clock detection.

A1-cbiss have a portfolio of gas detection systems which are proven, intrinsically safe, and to be used in harsh operating environments anywhere around the oil rig.

a1-cbiss can help select the most appropriate personal gas detectors to provide workers with continuous monitoring to improve safety and streamline compliance.

Emergency Response

In the event of an emergency, when response teams first arrive at a scene, it’s imperative they understand the risks present at the location, whether they’re responding to a fire, gas leak, chemical spill, or the unknown.

a1-cbiss offer an unknown hazards kit perfect for response teams to identify exactly which gases they are faced with.

Wearing a personal gas detector enables response teams to identify potential toxins in the air and leaking compounds.

Portable area gas detectors can also be used to set up a continuously monitored perimeter around the incident location, to provide real-time knowledge of what’s leaking, toxicity levels, and in which direction a gas cloud is dispersing.
