Final answer:
Yes, an applicator should be concerned with electrical sparks when applying space spray because they can create a fire or explosion hazard.
Step-by-step explanation:
An applicator must be concerned with electrical sparks when applying space spray. This statement is true. Space sprays, such as those used in pest control or paint application, often use aerosols or fine particles suspended in the air.
These particles can create a fire or explosion hazard if they come into contact with an ignition source, including electrical sparks. In industrial settings, especially involving flammable substances, spark-proof equipment and grounding of objects is important to prevent ignition from static or electrical sparks generated by the equipment or operator.
