1. Simultaneous operation of SE built in a row.Flexible construction allows SE to be setup almost anywhere.SE for crane repair
 The Safety Enclosure (SE) can be deployed by a 2
man team quickly and efficiently in almost any area;
 Scaffolding is used to prepare and define the work
area;
 Panels are of standard size 1m x 1m or 2m x 1m;
 Panels are constructed out of silicone coated fiber
glass fabric. They are light weight and flame
retardant;
 Industrial type fasteners and integrated Velcro seal-
ing strips are attached to each panel;
 High powered low noise blowers provide the posi-
tive pressure;
 Anti Static spiral hoses are used for routing the air
from blower to SE and for exhaust;
 Panel box, Internal lights and external blowers are
rated explosion proof;
 Panel Box will auto-shutdown when specific condi-
tions are met;
 Audio and Visual alarms will activate during shut-
down;
Fast & Efficient Deployment
 IEC 60076.17 compliant
 ABS (American Bureau of Shipping) certified
Gas Detection Certification
Gas analyzers are placed before the air intake blowers. This
is to prevent explosive or poisonous gasses from entering
the safe work zone within the Safety Enclosure (SE).
Workers entering the SE should also carry a personal gas
detector. If any gas is detected, the shutdown protocols can
be activated manually by pressing the emergency shutdown
button.
Personal gas detector Emergency STOP
Hot Work is one of the most dangerous
operations where oil and gas general con-
tractors can perform and continues to be a
principal source of fires and explosions
accountable for many of the industry's
most severe losses.
