    本标准为防护罩的设计、制造、安装提供主要技术依据。 
1　名词 
　1.1　危险区域(hazardous location) 
    人体进入后，可能引起致伤危险的空间区域。 
　1.2　防护罩的安全距离(safety distance of guard) 
    防护罩外缘与危险区域之间的直线距离。 
2　技术要求 
　2.1　防护罩结构和布局应设计合理，使人体不能直接进入危险区域。 
　2.2　防护罩应有足够的强度、刚度，一般应采用金属材料制造，在满足强度和刚度的条件下，也可用其他材料制造。 
　2.3　防护罩应尽量采用封闭结构，当现场需要采用网状结构时，其安全距离和网眼的开口宽度应符合下列要求： 
　2.3.1　为防止指尖误通过而造成伤害时，其开口宽度：直径及边长或椭圆形孔的短轴尺寸应小于6.5mm，安全距离应不小于35mm。 
　2.3.2　为防止手指误通过而造成伤害时，其开口宽度：直径及边长或椭圆形孔的短轴尺寸应小于12.5mm，安全距离应不小于92mm。 
　2.3.3　为防止手掌(不含第一掌指关节)误通过而造成伤害时，其开口宽度：直径及边长或椭圆形孔的短轴尺寸应小于20mm，安全距离应不小于135mm。 
　2.3.4　为防止上肢误通过而造成伤害时，其开口宽度：直径及边长或椭圆形孔的短轴尺寸应小于47mm，安全距离应不小于460mm 
　2.3.5　为防止足尖误通过而造成伤害时，防护罩底部与地面(或站立台面)的间隙应小于76mm，安全距离应不小于150mm。 
　2.4　一般情况下，应采用固定式防护罩，经常进行调节和维护的运动部件，应优先采用联锁式防护罩，条件不允许时，可采用开启式或可调式防护罩。 
　2.5　防护罩表面应光滑无毛刺和尖锐棱角，不应成为新的危险源。 
　2.6　防护罩不应影响视线和正常操作，应便于设备的检查和维修。 
　2.7　当防护罩需涂漆时，应按GB 6527.2-86《安全色使用导则》执行。
