SAFETY PRECAUTIONS

DANGER

THE FAN IS DESIGNED FOR PORTABLE AIR VENTILATION PURPOSES ONLY. THE FAN IS NOT DESIGNED

FOR TRANSPORTING LIQUID OR SEMI-SOLID MATERIALS. THE ELECTRIC MOTOR AND FAN HOUSING ARE

NOT DESIGNED FOR OPERATION IN AN EXPLOSIVE OR FLAMMABLE ATMOSPHERE. OPERATION OF

THE FAN IN AN EXPLOSIVE OR FLAMMABLE ATMOSPHERE MAY RESULT IN PROPERTY DAMAGE,

PERSONAL INJURY OR EVEN DEATH. INCORRECT USE OF THE FAN CAN RESULT IN AN ELECTRICAL

SHOCK AND/OR ELECTROCUTION. ALWAYS OPERATE THE FAN IN COMPLIANCE WITH CURRENT OSHA

AND NATIONAL ELECTRIC CODE REGULATIONS.

DANGER

INCORRECT USE OF THE FAN CAN RESULT IN PROPERTY DAMAGE, PERSONAL INJURY OR EVEN DEATH.

TO REDUCE THIS RISK, GIVE COMPLETE AND UNDIVIDED ATTENTION TO THE JOB AT HAND. AN

ENVIRONMENT ATMOSPHERE CONSTANTLY CHANGES. THEREFORE, IT'S RECOMMENDED THAT AIR

MONITORING/ GAS DETECTION EQUIPMENT BE USED FREQUENTLY. IF TESTS SHOW THAT THE

ATMOSPHERE QUALIFIES AS A HAZARDOUS LOCATION (AN AREA WHERE THE POSSIBILITY OF

EXPLOSION AND FIRE IS CREATED BY THE PRESENCE OF COMBUSTIBLE LIQUIDS, FLAMMABLE GASES,

VAPORS, DUST, FIBERS, FLAMES OR FILINGS.) DO NOT USE THIS FAN. READ AND UNDERSTAND THE

FOLLOWING PREPARATION ITEMS AND GENERAL SAFETY INFORMATION.

PREPARATION

1) Become familiar with the fan operations before utilizing this fan. Read and understand all cautions and warnings in this manual. Refer to current OSHA publications for complete job safety and health rules and regulations (CFR 1926 and 1910).

2) Confirm that the fan is in its original, factory configuration and has not been modified in any manner.

3) Minors should not be allowed to operate the fan. Close attention is necessary when used, especially when used near children or animals.
