A confined space is defined as an enclosed or partially enclosed space that is not intended as a place of work
It is liable to have an atmosphere that contains harmful contaminants or not contain a safe oxygen level.
It may have contents that could cause engulfment. It may have restricted means for entry and exit. Examples include: storage tanks, tank cars, process vessels, boilers, silos, pits, pipes, sewers, shafts, ducts, shipboard spaces.
Worksafe New Zealand have accepted
Australian Standard AS 2865:2009
Confined Spaces as the standard for confined spaced entry work in NZ.
By complying with this Standard, the principles for eliminating or controlling hazards will be compatible with obligations under the Health and Safety in Employment (HSE) Act.
AS 2865:2009 Confined Spaces emphasises that before a person enters a confined space, testing is carried out to ensure that:
(a) The confined space contains a safe level of oxygen;
(b) Atmospheric contaminants in the confined space are reduced to a safe level;
(c) The confined space is free from extremes of temperature;
(d) The concentration of flammable contaminant in the atmosphere is
0% of the Lower Explosive Limit (LEL) if hot work is to be carried out, or
10% if cold work is to be carried out.
The Workplace Exposure Standards
(WES) is intended to be used as guidelines for measuring atmospheric exposure levels of contaminants.
Employers under the HSE Act and the
HSNO Act must ensure that they have systems in place to control hazardous exposures in confined spaces this includes atmosphere monitoring.
TOXIC ATMOSPHERES
Contains gases, vapours, dusts or fumes that have poisonous effects on the body. Cleaning, painting or welding may produce dangerous vapours or fume. More people die from toxic gases than explosions caused by the ignition of flammable gas.
OXYGEN-DEFICIENT ATMOSPHERES
Can cause loss of consciousness and death. Oxygen deficiency can be caused by rust, fire, absorption by grain or soils, consumption by bacteria, and displacement by another gas.
FLAMMABLE OR EXPLOSIVE
ATMOSPHERES
Contains flammable gases, vapours or dusts which could be ignited by a spark or open flame. The risk of explosion or spontaneous combustion is increased if an oxygen-enriched atmosphere exists (where the oxygen content is greater than 23.5%).

It is recommended to bump test your gas detector before each use to confirm its ability to respond to gas.
Bump testing your gas detection instrument with calibration/bump gas is the only way to ensure the gas detector is working correctly and that you can be confident with the units operation.
Gas detectors should be calibrated at minimum every six months.
Calibrating your instrument compensates for factors such as temperature, humidity, length of service and gas exposure (which will affect the output of your sensor) and guarantees accurate readings.

Many explosive hazardous substances are toxic for humans, at levels markedly below the Lower
Explosive Limit (LEL) and cannot be detected at these levels by using only catalytic sensors.
Reliable detection of such substances in the ppm range can be accomplished using photoionization detectors (PIDs).

A PID measures VOCs and other toxic gases in low concentrations from ppb (parts per billion) up to
15,000ppm (parts per million or
1.5% v/v by volume).
A PID is a very sensitive broadspectrum monitor however a PID is not a selective monitor and has very little ability to differentiate between chemicals.

When deployed by RAE Systems Dedicated Wireless Network, MultiRAE instruments use a five-way notification system for gas (EC and IR sensors), radiation and man-down alarms to provide immediate and unmistakable notification system for gas, on-scene alerts while warning safety officers at a remote command centre. MultiRAE monitors provide personal and point detection capabilities for a broad range of applications and users (such as first responders, military, USAR, and industrial hygienists) making incident scenes safe by providing real-time and actionable data. Different models of the MultiRAE provide a unique combination of capabilities, including the ability to detect and meter gamma radiation in a multi-threat configuration.
MultiRAE monitors elevate worker and responder safety with real-time monitoring capabilities, parts per billion VOC detection for finding gas sources faster and an integrated man-down alarm for additional team safety.
