1.5.1 Ex certification and classification
Explosion-proof pumps have been approved by Baseefa (2001)
Ltd. in conformity with the essential health and safety require-
ments relating to the design and construction of equipment
intended for use in potentially explosive atmospheres given in

2. Safety

Pump installation in pits must be carried out by
specially trained persons.
Persons should not enter the installation area when
an explosive atmosphere is present.
For safety reasons, all work in pits must be supervised by a per-
son outside the pump pit.
Pits for submersible wastewater pumps contain wastewater with
toxic and/or disease-causing substances. Therefore, all persons
involved must wear appropriate personal protective equipment
and clothing and all work on and near the pump must be carried
out under strict observance of the hygiene regulations in force.
