The Permit Required Confined Space Decision Flow Chart is a tool for?
assistance in evaluating confined spaces
Two categories of hazards within a confined space are?
Atmospheric and non-atmospheric
What is a method of either controlling or monitoring atmospheric hazards within a confined space?
ventilation
How many cfm are minimum required for welding in a confined space without respirator protection?
2200 cfm
What is voltage level of RS-232?
RS-232 is ±3 to ±15, with a maximum short circuit survivability rating of ±25. Typical implementations see ±12. The negative voltage is the marking state, or the one state at the USART level. The positive voltage is the spacing state, or the zero state at the USART level. In terms of control signals, such at DTR or CTS, MARK (negative) is false, and SPACE (positive) is true. Zero volts is invalid, representing a break state.
Can we use 60 watt bulb in confined space?
As long as the fixture in the confined space is approved for confined space and the wattage rating of the fixture is not below 60 watts then there should be no problem using a 60 watt bulb in this situation.
How much is the light voltage in confined space?
The voltage can be any voltage that you like or what is available. It is the specifications of the light fixture that defines whether it is suitable to be used in a confined space. One has to know what the environment is in the confined space before a light fixture can be chosen. The environmental conditions can be any one of a number of conditions including explosive gases. With explosive gases present, the wiring and devices within the space must all be explosion proof equipment.
What type of extinguisher should be avoided in confined space?
CO2
What is confind space?
Confined space is an area that is enclosed. A dog kennel could be a confined space for a dog. A living room is a confined space for example.
Why 24 volts light to be used in confined space?
It is to reduce the impact of electrical shock to the workers (in case any). By having less voltage the consequence would also be diminished. Installation with higher voltage (110 V, 220 V, or 380 V) is possible to create a fatal incident depending upon the environment (wet, metal surface, etc.)
Fearful of being in a confined space or tight space?
The fear of being in a confined or tight space is claustrophobia.
Who is responsible for coordinating the installation confined space program?
the confined space program team (CSPT)
Where can i find confined space gas detectors?
There is currently a sale on confined space gas detectors at pksafety. They have several models to choose from: http://www.pksafety.com/confined-space-gas-detectors.html
What best describes the term entry supervisor specifically pertaining to the USF Confined Space Program?
an authorized employee responsible for determining whether acceptable entry conditions are present in a confined space before authorizing entry; overseeing the confined space operation, and terminating the confined space entry
Which of the following is NOT required from confined space entrants?
ensure that a qualified person evaluates and classifies the confined space
What would qualify as a confined space rescue?
Confined space is an area which is enclosed with limited access which makes it a dangerous place to be in. Therefore, confined space rescue refers to techniques to save people whos been trapped in confined spaces.
What is the pressure exerted by a vapor confined within a given space?
pressure exerted by a vapor confined within a given space
