3 Minimum access openings
The dimensions shown in 11 to 14 are the recommended minimum for limited activity through the opening. Larger openings will be needed in specific instances, depending upon the nature of the task, size and mass of the parts, etc. Such larger openings can be more useful and allow greater efficiency.
The larger openings for access with arctic clothing are for earth-moving machines and equipment intended for use in cold environments.
Based on available anthropometric data, the recommended openings, in figures 1 to 5, are the smallest that will accommodate the 95th percentile operator as defined in ISO 3411.
In all cases in 11 to 3,4., all corners may have an optional maximum 25 mm radius.
