WHY MEASURE? The CAP1145 directive indicated that from 1 April 2015 the Civil Aviation Authority would prohibit helicopter operators from carrying passengers on offshore flights whose body size, including required safety and survival equipment, is incompatible with push- out window emergency exit size. This measurement programme addresses this issue by providing the information necessary to designate XBR from non-XBR individuals.
WHAT TO MEASURE? Shoulder breadth is accepted as the anatomical dimension most limiting egress through a confined space. It is suitable for measuring both men and women. It is more reliably measured than other measurements. Measuring against the skin surface is more reliable than over clothing. Measuring without compressing the surface is more reliable than exerting a force to reduce the measurement.
The measuring Instrument is a SECA measuring rod model 207, a form of ‘Large sliding caliper’. It features a large area on the caliper branches for measuring the convex surface of the shoulder, which makes measurement more straightforward THE INSTRUMENT Step Change in Safety has already ordered 300 on behalf of industry and can be purchased from us at Cost + shipping and handling (-30% OEM cost)
THE PROTOCOL Definition The linear distance between the most lateral points on the skin surface R and L deltoid muscles. Participant presentation and position Male participants may be measured bare-chested; female participants are required to wear a sleeveless top or equivalent garment which provides access to measuring the deltoid muscles. Participants stand erect with feet together and arms against the sides, with hands in the mid-prone position (i.e. thumbs pointing forwards) resting on the lateral thighs. Measurer position The measurer stands in front of the participant and observes the deltoids at eye level. Measurement Viewed directly from the front, identify the most lateral point of the protrusion of deltoid muscle as observed on L and R sides. Opening the large sliding caliper beyond the anticipated distance, slowly move the branches towards one another until they rest on the skin surface. Record the measurement to 0.1 cm precision after a normal expiration. Stewart, A. D. & Hume, P.A. (2014). Bideltoid Breadth Measurement, J.E.

RECORDING THE MEASUREMENT Ensure the appropriate form is to hand, with pre- information already completed (including VANTAGE numbers) Beginning at measure 1: transcribe the measurement, filling in one digit per box Note the measurement is in cm, and recorded to 0.1 cm Continue to measurement 2 Calculate if this is 1% greater or lesser than measurement 1, and determine if a third measurement is required. Perform a third measure and transcribe as before

KEY POINTS - RECAP Communicate with your workforce regarding the measurement strategy Contact / Engage with your Occupational Health professionals to make sure they are aware of the train the trainer sessions be able to train the measurers (medics). Communicate with your Medics. Make sure they are fully up to date and able to receive the training from the right people And Engage with Step Change in Safety with regard to requirements for callipers
