kesava & dipil sir,
good to read the disscusion & i m benefeted oo. i think some time we go in too technical details of some but forget the basics.
thanx dipil for raising such a nice questions & hope all safety proffessionals will be encouraged & motivated to ask even silly questions which may be useful too.

Dear Savisudh,
I am attaching a short ppt presentation on confined space with which you will be able to understand the approach. In case you want to train anyone ppt alone is not enough. Confined space work may involve IDLH(Immediately dangerous to life and health) situation. There are very many kinds of confined spaces and the safety precautions may vary from one to other. A safety person with perfect knowledge alone may try to impart training in such cases.
The norms for confined space :
HIp (hazard identifican plan)
JSA
Training for entry supervisor, Entrant and Standby man
Rescue team
Confined space entry permit and other permits as to the
nature of job(Hot permit, cold permit and so on)
Following permit conditions religiously.
As to safety quizes there are many. general and topic wise. In case you specify I may be able to help.

Dear Sir
Nice & very usefull posting.
Few questions from the attachement:
1. If the Oxygen percentage is more than 23.5 % what all health hazard can come?
2. In what all situations/which types of jobs this can happen?
3. Tailboard Briefing is that same of Tool Box Meeting?
Hope to get a positive reply.

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

thank you Kesava sir,
coz i was thinking that if O2 will be more than 23.5%, there will be no health hazard but yes i was knowing about fire hazard only.I thought that whether o2 level is more,our lungs are designed so that it will take only that % of O2 for which they are designed.
Thanx for information.

Dear Sir
Thanks for the reply with technical explanations.
Some more query please:
1. In confined spaces normally we suggest 24V supply. Almost all the places where I see confined spaces, even in our plant is being used 24 V supply for lighitng. But in case of grinding and drilling operations, the drilling machine & drilling machine runs with 230 V supply. So is this safe? Or else is any other alternative avilable as on today in industry?
2. Tool Box Talk and PEP talk are same or if not, whats the difference?
Hope to get a positive reply.

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 is no hard and fast rules in dealing with confined spaces. All confined spaces can not be treated equally. Every confined space may have its own inherent hazards. A competent safetyman has to check and decide on safety precautions and permit issuer will have to decide up on what kind of electrical energy can be permitted. Use 110 volt for lightings with GFCI during the grass root operations and intrinsically safe (non-spark producing) 24 volt during situations where even traces of hydro carbon, flammable, and explosive atmospheres exist. When using portable electrical tools, be sure they are double insulated; and connected to a portable leakage protection unit. Suspend all electric power cables so they do not create a trip hazard.
An excavation just 4 feet in depth is now considered confined space. Excavation is normally done mechanically. In such places using 230V is safe and permitted. Use the discretion. It is your judgement that is important.
Toll box talk is planned, prepared, often scheduled. Pep talk is just casual .

Dear Hansa
Thanks for the reply... pneumatic grinder is there, but I think most of the indian industries not using this... Even in our site we are using grinder with 230 v supply inside confined spaces... only thing we are ensuring in this case, the cable should be in good condition and must be without any joint...
However we may can think about implementing this,...
