In the first place, the responsibility for ensuring Safety A. Common A. Standards Starting Starting lies not with employees but with corporations. Not only human errors and Subject Matter Standards Starting Basic Safety mechanical failures but also risks themselves should be reduced. Such Basic Safety KOSTAC Safety Standards AZ-C1 concepts originating from Europe and the United States are also gradually Standards Point Point spreading among Japanese corporations.
