Standards

AS 1336 should be amended to require:

• wide-vision goggles to be used for metal buffing and grinding operations where wide-vision spectacles can not be fitted with a gap of less than 1 mm;
• all spectacle-type eyewear to be fitted so that a gap of no more than 1 mm exists between the face and the eyewear at any point where particulate material can enter;
• eyewear that meets medium impact requirements, as amended to reduce gaps, be used for spot or resistance welding operations.

AS 1337 should be amended to include greater details of the head-form, including maximum cheek depth and brow to cheek measurements in both the vertical and horizontal plane. In addition, the 95th percentile sizes for Australian males and females separately, should be clearly marked on the head-form diagram. Other measurements may also be required to provide an adequate model for designing eyewear that will fit a range of workers. The head-form measurements and confidence intervals should be based on both male and female populations of 15 years and above to cater for the needs of young workers. This would assist designers to consider the curvature of lenses needed to achieve proper fit for the full range of workers and trainees.
