In foul weather and low light conditions, work zones that put workers in close proximity to oncoming traffic create a tremendous work hazard. To protect the worker, you must maximise a driver's reaction time. The worker needs to be visible to the oncoming traffic even when the job at hand diverts the worker's attention away from the oncoming traffic. High visibility work wear is necessary to create contrast between the worker and the work zone.
The ANSI 107 standard establishes a set of performance criteria for high visibility apparel. The standard defines three garment categories that are based on worker hazards and tasks, complexity of the work environment or background and vehicular traffic and speed.
Class 1 Garments - are intended for use in activities that permit the wearer's full and undivided attention to approaching traffic and where there is ample separation of the worker from traffic, which should be traveling no faster than 40kph (25mph).
Class 2 Garments - are intended for use in activities where greater visibility is necessary during inclement weather conditions or in work environments with risks that exceed Class 1. Garments in this class also cover workers who perform tasks that divert their attention from approaching traffic, or put them in close proximity to passing vehicles traveling at 40kph (25mph) or higher.
Class 3 Garments - provide the highest level of visibility and are intended for workers who face serious hazards and often have high task loads that require attention away from their work.
Envisage™ garments in Fluorescent Lime Yellow or Fluorescent Orange provide excellent worker day/night visibility and both fabrics comply with ANSI 107 Class 3 Level 2.
ASTM E96/E96M Standard Test Methods for Water Vapour Transmission of Materials
These test methods cover the determination of water vapourtransmission (WVT) of materials through which the passage of water vapour may be of importance, such as paper, plastic films, other sheet materials, fibreboards, gypsum and plaster products, wood products and plastics.
Significance of Use
The purpose of these tests is to obtain, by means of simple apparatus, reliable values of water vapour transfer through permeable and semi-permeable materials, expressed in suitable units. These values are for use in design, manufacture and marketing. A permeance value obtained under one set of test conditions may not indicate the value under a different set of conditions. For this reason, the test conditions should be selected that most closely approach the conditions of use.
Non-breathable rainwear is designed to keep water out but also keep perspiration in. It creates an internal environment that stores heat which leads to workers becoming wet from perspiration even though no rain has passed through. Breathable rainwear is designed to collect and transmit perspiration out of the garment. This leaves the worker dry from both the transmitted perspiration and the rain.
Breathability is measured in two ways –
Moisture Vapour Transmission Rate (MVTR) – the amount of vapour that evaporates through the material per ASTM E96.
Total Heat Loss (THL) – the ability of a material to release heat as it is built up per ASTM F1868.
For a material to be considered breathable, it must have a:
Moisture Vapour Transmission Rate (MVTR) of greater than 5000 g/m2/24 hours.
Total Heat Loss (THL) of 300 watts/m2/24 hours and
To be marketed as being breathable, rainwear must be tested according to ASTM E95 procedure BW and the results reported.
Material must withstand water pressure of 30 psig without leaking. The seams of the rainwear must not exhibit any evidence of leakage when exposed to water at 3 psig for two (2) minutes.
