ECO members must be identifiable by coloured apparel (helmets, caps, hats, vests or tabards) used consistently throughout the facility; in-house first aiders who respond with the wardens show a white cross on green, and apparel should show the wearer's ECO title. Table 5.1 lists white for the chief warden, deputy and communications officer, yellow for floor or area wardens and red for wardens.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
