How much hazard you identify in confined space like toxic and flammable gases??? What is the LEL and how much ppm of gases???

Question

Accepted Answer

As a Safety Officer, I am trained to identify hazards in confined spaces like toxic and flammable gases.

I have extensive knowledge of the different types of toxic and flammable gases that can be present in confined spaces.
I am familiar with the methods and equipment used to detect and measure gas concentrations, such as gas detectors and sampling techniques.
I understand the concept of Lower Explosive Limit (LEL), which is the minimum concentration of a flammable gas or vapor in air that can ignite.
I am aware of the permissible exposure limits (ppm) for various gases, which indicate the maximum concentration workers can be exposed to without adverse effects.
I prioritize regular monitoring and testing of confined spaces to ensure gas levels are within safe limits.
I have experience in implementing control measures to mitigate the risks associated with toxic and flammable gases, such as ventilation systems and personal protective equipment.

Accepted Answer

Oxygen 19.5% to 23.5%
  co2 - 30 PPm
 ch4,- 0.5 %
H2S - 10 PPM gasses level checked. 
 EEBD , SCBA kit provided and emergency access must be provided and rescue team  . Emergency lights,  ventilation should be provided,  cominecation system implementation 
Man bucket should be available,  permit system and tally board system must be installed

Accepted Answer

oxygen level should be in 19.5% to 23.5% n there should be no toxic gas present like h2s a harmful toxic gas it should be below 10% of ppm to reduce any incident proper ventillation and proper lighting should be used lamp only of 24volts not beyond and a safe to go tag outside ta manhole of confined space shoudl be display

Accepted Answer

Oxygen concentration between 19.5% and 23.5%

Flammable gas concentration less than 10% of LEL.

Airborne dust concentration less than LFL (5 feet)

Toxic gas Concentration less than PEL.

Accepted Answer

Flamable, toxic,rritant, Asphyxiating

Different combustible gases have different lower explosive limit concentrations. methane, propane is the lower explosive
