Ah yes, the Confined tab! The Confined tab is the ninth tab of the PTW system. It contains Section 10 of the PTW, which deals with confined space entry work of the PTW and is found in the following place on the PTW tab:
The Confined tab is the fifth specific activity tab of the PTW. This tab is only selected when confined space entry View Full Answer
A very important question! The Confined tab of the PTW must be selected whenever any confined space entry is included in any of the work processes the contractor does. Confined space entry work is considered 'high risk' because every year persons are killed or seriously injured either in confined spaces themselves or in attempting to rescue persons trapped in confined spaces.CONFINED SP View Full Answer
Yep, now let's look at the confined tab in a bit more depth! Great! Let's get on with it! All confined space entry processes, which are required for the work being done, are managed in the Confined tab (section 10). This tab consists of five parts:1. Work Environment section - this section identifies the type of confined space and the type of environment into which the confined space en View Full Answer
Sure thing! Let's take a closer look at this section then. The first thing which needs to be done is to examine the type of confined space which will be entered and to determine what the confined environment will be in order to determine the potential hazards associated with the confined space work being done.This work environment section does this and is very quick and easy to complete View Full Answer
Okay! Let's take a closer look at this section. Once the confined space work hazards, for the work being done, have been identified, the necessary checks and controls to any confined space work performed is safe, must be confirmed and checked.The Precautionary Safety Measures section is where these safety measures are determined and confirmed. The Permit Issuer and Permit Requester work View Full Answer
Okay! The Contractor Confirmation section again. This is a very important section because it is where the Permit Requester (PR) confirms that all the required safety precautions, relating to standard or complex hot work, are in place and confirms this formally. It is also important because the Permit Issuer (PI) also confirms formally that he agrees with the actions taken by the PR and View Full Answer
Oh yes, this is a really important question! The Hot Work tab has both layer 1 and layer 2 effects in its workings. The layer 2 effects have been explained in detail in the Precautionary Measures question (refer to this section for more details), so we'll concentrate on the layer 1 effects:The layer 1 effects from this tab are connected to the Approve tab and are both passive and active View Full Answer
This is a great question and a really important one too! The vessel specific precautions section is important because it becomes an important factor when more complex work needs to be done and new hazards and safety precautions need to be reviewed to account for this.The vessel specific precautions apply to two tabs in the Permit to Work (PTW): 1/. Hot Work - where vessels, tanks o View Full Answer
Ahh yes, this is where the hot work becomes complex! The vessel specific precautions section must be used when any hot work is to be done on a vessel, tank or piping where there is a likelihood that the vessel, tank or piping contained a substance which could be reactive to the heat of the hot work process and cause either a fire to break out or an explosion to take place.The vessel spe View Full Answer
So, you want to get into the vessel specific precautions section some more, great! When choosing an existing vessel, its' details will pull through into the vessel section, which means we don't have to add its' basic descriptive details. In order to select a vessel, the vessel specific precautions section must be visible first.Note, when we refer to a vessel, we can also mean a tank or View Full Answer
Ahh, the vessel specific precautions section, great! When adding a new vessel, it will have no basic descriptive details so these will have to be added in the vessel section. In order to add a new vessel, tank or piping to it, the vessel specific precautions section must be visible first.Note, going forward, when we refer to a vessel, we can also mean a tank or piping; it just keeps thi View Full Answer
Ahh yes, the first part of the vessel section! Let's go! The vessel details section contains details about the vessel itself, which should be entered already. If they are not complete, these are simple and easy to add.The next part of the vessel details section identifies the contents which are or were present in the vessel, as well as, how these exist and what hazards they present in t View Full Answer
Ahh yep, the second part of the vessel section! Great, let's go! The vessel isolation details section contains details about isolation of the vessel. In this section we can record who the responsible persons are for the vessel being isolated, we can record the isolation point(s) which need to be in place for the vessel to be isolated and made safe, we can confirm the safety precaution c View Full Answer
Ahh yes, the third and final part of the vessel section! We're almost done, so let's go! The measurement details section contains details about the measurements made of the contents of the vessel. These measurement details are important because they can show evidence that the contents of the vessel were determined to be safe before work began. This allows both the contractor and client View Full Answer
Ahh yes, recording temperature measurements! Great stuff, let's go! When the temperature measurement type is selected, readings are entered, which relate to the temperature of contents in the vessel. These readings are recorded in degrees Centigrade and should be at an approximate value of 25 degrees C, to ensure the work being done is safe.The actual temperature measurement type looks View Full Answer
Ahh yes, recording pressure measurements! Great, let's go! When the pressure measurement type is selected, readings are entered, which relate to the pressure of the contents in the vessel. These readings can be recorded in either Pascals (Pa) or kilo-Pascals (kPa) and should be at an approximate value of 101.325 kPa (the value of the normal pressure around us), to ensure the work being View Full Answer
Ahh yes, recording acidity measurements! Great, let's go! When the acidity measurement type is selected, readings are entered, which relate to the acidity (or basic) nature of the contents in the vessel. These readings are recorded in pH and should be at an approximate value of 7.2 pH, to ensure the work being done is safe. In this case, to prevent a person from being exposed to acidic View Full Answer
Ahh yes, recording radioactivity measurements! Great stuff, let's go! When the radioactivity measurement type is selected, readings are entered, which relate to the temperature of contents in the vessel. These readings should be at an approximate value, which ensures the work being done is safe. In this case, to prevent a person from being exposed to excessive radioactivity.The actual r View Full Answer
Ahh yes, recording concentration measurements! These can be a bit trickier because the contents being measured may be a single component (ethane gas) or they may be more than one component (a mixture of methane and air). When there is more than one component present in the contents, these can be potentially more dangerous and so each component may need to be measured to ensure that the View Full Answer

Ahh yes, this is very easy to do! Each measurement type has a red CLOSE button at the top right of it. Simply click on this button and the measurement type will be removed from the vessel section:
View Full Answer
Ahh good question! The reset button allows all the measurement types currently set-up in that particular vessel, to be cleared and removed. Once done, all measurement types will have to be set-up again:

Okay, no problems! A measurement type can easily be changed from the Unit Type drop-down field in the measurement type. Simply click on the drop-down field and select the desired measurement type from the list. Once you click on the new option, the PTW will display a pop-up to confirm that your new selection. Click OK to continue the change:
