Dear Sir,
Thank you for your reply. Now the situation is clear. So, if we calculate according to the 39th Celebrations, I believe the first foundation day celebration took place in 1971. If there are any corrections, please let me know.

Kesava & Dipil Sir,
Good to read the discussion and I'm benefited too. I think sometimes we delve too deep into technical details and overlook the basics.
Thank you, Dipil, for posing such insightful questions. I hope all safety professionals will be encouraged and motivated to ask even seemingly simple questions that can also be valuable.

Dear Savisudh,
I am attaching a short PPT presentation on confined space, which will help you understand the approach. However, if you intend to train someone, a PPT alone may not be sufficient. Confined space work can involve IDLH (Immediately Dangerous to Life and Health) situations. There are various types of confined spaces, and safety precautions may vary from one to another. In such cases, only a safety professional with thorough knowledge should conduct the training.
The norms for confined spaces include:
- HIP (Hazard Identification Plan)
- JSA
- Training for entry supervisor, entrant, and standby personnel
- Rescue team
- Confined space entry permit and other permits based on the nature of the job (e.g., Hot permit, Cold permit, etc.)
- Strict adherence to permit conditions
Regarding safety quizzes, there are many general and topic-specific ones. If you specify, I can provide assistance.

Dear Sir,
Nice and very useful posting.
Few questions from the attachment:
1. If the oxygen percentage is more than 23.5%, what health hazards can occur?
2. In what situations or types of jobs can this happen?
3. Is Tailboard Briefing the same as a Tool Box Meeting?
Hope to receive a positive reply.

Dear Dipil,
As a health hazard, it has been discovered that the delivery of higher concentration and high pressure can cause hypoxia from pulmonary damage, as well as causing visual damage and central nervous derangement. Oxygen in excess of 23.5% is usually considered a fire hazard. Clothing and hair can easily catch fire in an O2 enriched atmosphere. Textiles can burn fiercely when they are enriched with oxygen.
Oxygen enrichment happens very rarely. By accident, chemical reactions, passing purposely, and failing to monitor, there are chances of O2 enrichment. Toolbox meetings are conducted on specific topics with a different purpose. It is a kind of training. However, a tailboard meeting is to instruct, clarify, and make sure that everyone involved is clear about what to do regarding the job at hand just before starting it.

Thank you, Kesava, sir,
I was under the impression that if the O2 level exceeds 23.5%, there would be no health hazard. However, I was aware of the fire hazard only. I believed that our lungs are designed to intake only the percentage of O2 for which they are designed.
Thank you for the information.

Dear Mr. Keshav Pillai,
Thank you for your response and technical explanations. I have a few more queries:
1. In confined spaces, we typically recommend a 24V supply. In most confined spaces I have observed, including those within our plant, 24V supply is used for lighting. However, for grinding and drilling operations, the machines run on 230V supply. Is this safe, or are there alternative options available in the industry today?
2. Are Tool Box Talks and PEP Talks the same, or if not, what are the differences between them?
I look forward to your positive response.

Dipil, it not safe to use 230 V supply grinder.We can use pneumatic grinder instead. m i right kesava sir. Regards, Hansa

Dear friends,
There are no hard and fast rules in dealing with confined spaces. Not all confined spaces can be treated equally, as each may have its own inherent hazards. A competent safety professional must check and determine the necessary safety precautions, while the permit issuer must decide on the type of electrical energy that can be permitted. Use 110 volts for lighting with a Ground Fault Circuit Interrupter (GFCI) during grassroots operations, and intrinsically safe (non-spark producing) 24 volts in situations where even traces of hydrocarbons, flammable materials, and explosive atmospheres are present. Ensure that portable electrical tools are double insulated and connected to a portable leakage protection unit. Suspend all electric power cables to prevent them from creating a trip hazard.
An excavation just 4 feet in depth is now considered a confined space. Excavations are typically done mechanically, and in such cases, using 230V is safe and permitted. Use your discretion; your judgment is crucial.
A toolbox talk is planned, prepared, and often scheduled, while a pep talk is more casual.

Dear Hansa,
Thank you for the reply. A pneumatic grinder is available, but I believe that most Indian industries are not using it. Even on our site, we are using a grinder with a 230 V supply in confined spaces. The key consideration in this case is to ensure that the cable is in good condition and without any joints.
However, we may consider implementing this in the future.
