According to the UK Health and Safety Executive, a confined space can be any space of an enclosed nature where there is a risk of harm from hazardous substances or dangerous conditions (e.g. a lack of oxygen). This could include storage tanks, sewers, manholes, tunnels, ship voids, pipelines, silos, wells and pits. Each day, workers in almost every industry conduct work in such spaces and when opening hatches, removing covers or lowering into trenches, they can often be put at risk of exposure to hazardous gases.
For oil and gas personnel, managing and detecting potential hazards such as this – especially flammable and harmful gases – is a matter of daily practice. Best practice and the Confined Spaces Regulations 1997 both say that, if entry is necessary, the air inside the space should be tested to ensure that it is safe prior to going inside.
Confined space kit
Industrial Scientific’s Ventis™ MX4 multi-gas detector is well-established in the field of personal gas detection. Adding value and versatility, the Ventis can now be used more easily for confined space entries as well as personal monitoring using the Ventis Confined Space Kit with Ventis Slide-on Pump. The kit provides users with everything needed to operate the instrument as a personal monitor and/or for use in confined space entry, as well as perform calibrations and bump tests.
The package includes the Ventis with sensors; the Ventis Slide-on Pump; a 110 VAC desktop charger for each rechargeable monitor or pump ordered (max of 2); a calibration cup and tubing with T-fitting; a dust filter/water stop; 10 feet of sample tubing; a 34-litre cylinder of calibration gas; a manual regulator; and a rugged, hard plastic carrying case.
The Ventis, originally introduced in 2011, is a lightweight, highly configurable instrument that is capable of detecting one to four gases at once, including oxygen and combustible gases and toxic gases such as carbon monoxide, hydrogen sulphide, sulphur dioxide and nitrogen dioxide. A backlit LCD allows the user to view readings from all four sensors simultaneously. Audible, visual and vibrating alarms indicate when atmospheric conditions are unsafe for entry into the space.
The Ventis is also compatible with iNet®, Industrial Scientific’s subscription-based gas detection program. iNet provides peace of mind that equipment is properly maintained and serviced, and allows operators to review and/or provide required records on demand. Most importantly, it ensures that staffs are kept safe from hazardous gases with real-time alerts.
