We all know, The confined spaces can be deadly.

Many people are killed or seriously injured in confined spaces.

These fatal accidents happened across a range of industries; from complex plants to simple storage vessels. Those killed were not only people who worked in the confined spaces but also those who tried to rescue them. Therefore, it is important to implement good safety practices to ensure a safe working environment for everyone in the confined space.

The prime requirements is an communication, An effective and reliable means of communication among entrants inside the confined space, and between entrants and attendants, is required. When choosing a means of communication, it is advisable to give careful consideration to all anticipated conditions inside the confined space (e.g.,visibility, possibility of a flammable atmosphere, and noise levels) and to the personal protective equipment in use (e.g., ear muffs and breathing apparatus).

Ensure two way communication always. The communication system used can be based on speech, hand signals, telephone, radio, and so on. Whatever system is used, it is important that all messages can be communicated easily, rapidly and unmistakably between relevant people. It is important to take note on the limited penetration of radio signals into buildings, vessels and below-ground structures. The advantages of having a person outside the confined space in direct voice and visual contact with the entrants are clear. This also facilitates the monitoring of entrants for the symptoms or behavioural effects of exposure to hazards.

Maintain the communication very simple & effective. It is important that confined space entrant(s) are informed quickly if a situation arises on the outside which could endanger the entrants, such as problems with a supplied air system or ventilation system.

It is essential that the means of raising the alarm and setting in motion the emergency rescue procedures are effective and reliable. It is also necessary that the line of communication be available at all times during the work. It is required to have an appropriate means of communication between the person working inside a confined space and the attendant stationed outside, whether by voice, rope tugging, tapping or by a battery-operated communication system specially designed for confined space use. Note that radio frequency/wireless devices do not work effectively in confined spaces such as tanks or sewers, where there is metal or concrete shielding between the interior of the space and the outside.

Use latest technological devices. Body alarm devices may be useful in a confined space where communication between entrants and attendants is difficult. These are designed to sound if the wearer does not move during a specified period of time.
