TTA220 Portfolio
Welcome to my TTA220 Portfolio. Here you will find various documents, diagrams and scale drawings for my TTA220 module. You can click on pictures and documents to enlarge them so they can be viewed in greater detail. For the best results in checking scale drawings, there is a PDF download button next to them so you can download them to view the drawings at the correct size. I have also included dropbox links for my WYSIWYG files, if you wish to view those as well.
Graduation 2019
In this labelled drawing for the Falmouth University graduation of 2019 I have commented on how all the chairs have been connected. Table 10 in section C2 (seating and gangways) of the technical standards for places of entertainment by the Association of British Theatre Technicians (ABTT) shows that with over 600 seats that all seats should be individually fixed to the floor. This was not reasonably practicable at graduation as it is temporary seating on a specialised sports hall floor, therefore seats can’t be fixed to the floor. Instead, all the seats in one row had been fixed together. This was acceptable as the audience would not be lively, due to it being a sit-down graduation ceremony. In the bottom of this table it says what should be done in this situation, which is what was complied with. This is important as it stops seating rows from buckling or snaking when under pressure during an evacuation etc.
In Table 9 of the same section it also tells us how many seats you can have in a row with a gangway on either one side or both sides in correspondence to the seatway width that was used. The maximum number of seats we had in each row was 15 therefore a gangway had to be on both sides as you can’t have more than 12 seats if escape is only possible in one direction. The table also tells us the seatway width we had to comply to. As the seats that were used were non-foldable, the seatway width used was between 323mm and 349mm. This is measured from the edge of the seat to the back of the seat In front. If the seats are foldable it is measured from the arm rest to the back of the seat in front, as when the seat folds, the furthest point forward should be the arm rest.
Studio A
This is a labelled drawing of Studio A in the Academy of Music and Theatre Arts at Falmouth University. On this drawing I have shown the gangways between the seating blocks and the way in which the public should exit these blocks during an evacuation. In section C2.21 of the Technical Standards book by the ABTT, it states that any gangways should not be stepped or have a different slope of that where the seating meets the gangway. It also states that all steps from seating should be at right angles from the line of travel along the seating. As shown in the diagram the seating and gangways of studio A all comply to this rule. This is important as if it is dark when evacuating, it is easy to navigate the way out of a seating block safely. It also states all gangways should be no less that 1100mm wide, which this studio is also in compliance to.
Graduation 2019 Risk Assesement
On the left is a risk assessment for the Falmouth 2019 Graduation. Risk assessments are an important document. As I have learnt on the IOSH (Institution of Occupational Safety and Health) course, there is no set way of doing a risk assessment, but you must cover that checks were made, who could be affected, how risks are dealt with, if the precautions are reasonable and who is involved in taking actions on the control measures. In a court of law, a risk assessment will show that you have taken precautions against something happening and if that something was to happen and people were not following the control measures in the risk assessment, it enables you to prove that you have done what is needed and that it is the persons fault who was not following the control measures stated in the risk assessment.
ADA Risk Assesement
In section 8.3 of the purple guide, it says to make sure that the risks from work at height are assessed, and appropriate work equipment is selected and used. This has been reflected in the risk assessment to the right, as the risks have been identified and one of the control measures states that the correct equipment should be used and that is inspected regularly.
Source Four Diagram
On the left is a diagram of a source four lantern showing its component parts including some safety information. The risk assessment for this can be found below.
Source Four Risk Assesement
In this risk assessment I have talked about how only trained persons should be able service lanterns when live, due to the risk of electric shock. In section 11.16 of the purple guide, it talks about access to electrical equipment. The main part relating to this risk assessment is access to dimmers, as this is what would be used when testing lanterns. It states it should be restricted to those people competent to operate the equipment. This reference shows my risk assessment corresponds with health and safety law highlighted in the purple guide.
Scaffold Tower
On the left is a diagram of an aluminium scaffold tower showing its component parts including some safety information. The risk assessment and safe system of work for this can be found below.
Scaffold Tower Risk Assesement
In section 9.5 of the purple guide, it states that, depending on the type of structure, the Manual Handling Operations Regulations 1992 may apply. As a scaffold tower is built from the ground up by passing and carrying parts of the tower to the top to build, it falls under these regulations, therefore it especially has to be highlighted in the risk assessment so as to comply with these regulations and health and safety law.
Scaffold Tower Safe System of Work
A safe system of work is important as it tells whoever is doing the task what to do and how to do it safely. It briefly describes the task and gives instructions on how to do it, then states the hazards associated with the task at hand and then gives control measures on how to avoid these hazards. The safe system of work is then monitored constantly to make sure what it is doing is effective. It is then reviewed periodically and any changes that need to be made will be done. From the IOSH course, I have learnt that this is the last thing that should be done in relation to the hierarchy of control, but they are still mandatory as they help reduce or eliminate exposure to hazards.
I have included a link to a word document containing a word count for the report on this page.
