The immaculate workshop and well-ordered equipment suggest dedication to high levels of work efficiency. We see blotches of blue everywhere with the familiar shape of CEJN reels. Our companion points out that they bought 120 hose reels and cable reels 3-4 years ago to clear the floor from the hose, preventing you from tripping.

This customer had already contacted our sales subsidiary CEJN Far East about six months ago after a Google search for guns with a low noise level, compliant with OSHA (safety and health at work) requirements regarding reduction to a pressure of 2 bar. (30 psi) in case of blocked tip. The manufacturing department used 130 guns that needed to be replaced to prevent employee injury in potential clogged tip situations.

Greater safety for staff
To adapt to the application and ensure operator safety, management decided that the CEJN Series 208 blowing gun should be customized with an extension tube and protective shield. There are several stations equipped with low-noise guns which are mainly used to remove chips, oil or coolant for excess cooling. Each station has different requirements and uses extension tubes of different lengths to perform the tasks. Screens have also been provided to protect workers from flying fragments, as an additional protection to the safety goggles necessarily mandatory in the workshop.

Using the blow gun is an integral part of daily work
Stopping at a station near a numerically controlled machine, an operator engaged in the exercise of his duties, who knows perfectly by heart, tells us at intervals between one procedure and another the frequency with which he uses the low-noise gun.

Excess coolant must be removed frequently with the gun at each pass, and not even the operator is able to estimate how many times the tool is used per day. When asked what the experience of using the gun is, he replies “It works perfectly and is much quieter than the previous one”.

Efficiency at work
We also saw an operator with 3 years of experience cleaning components collected in numerous aligned containers. He smiles as he tells us that the high flow of the low-noise guns helps him work efficiently. Some of the components it cleans are pipes over a meter long, and high flow is critical to being able to do a thorough job. Before leaving him to his responsibilities we asked him if improvements could be made and he replied that a longer tube would not be bad.

1. Controlled rewind
hose reels, preferably installed in a suspended position The use of an automatic rewind hose reel reduces the risk of hoses and cables remaining on the floor when not in use. It is preferable that the hose reels are installed in a suspended position, so as not to clutter the floor and make them easily accessible to operators.

2. Brightly colored hoses (high visibility)
Hoses should always be rewound securely into the hose reel when not in use. In the event that it is necessary to leave the hoses unwound on the floor, these should be of a color that stands out to make them more visible, allowing operators to pass or step on them, avoiding tripping. A high visibility hose is designed to be easily spotted on most surfaces or in poorly lit areas. If the danger is identified, it can be avoided.

3. Hose reel with controlled rewind
A hose reel with controlled rewind allows a safe and guided recovery of the hose in its casing. It can prevent injury to operators and damage that quick couplers or tools attached to the hose can cause to surrounding surfaces during uncontrolled rewinding of the hose.

4. Fall arrest ball
Any tools connected to pipes lying on the floor are a potential injury hazard. The stop ball placed on the hose of the reels can also be a hazard. Generally, the winders are equipped with a rigid spherical or cylindrical stop ball. Accidentally stepping on it creates the risk of tripping or injury such as sprains or strains. The use of a hose reel with a soft stop ball, which collapses under the operator’s weight, therefore minimizes accidents.

5. Protective
covers to avoid damage to surrounding objects The use of soft protective covers on the quick couplings protects the surrounding objects and surfaces and also the quick couplings are protected from any external factors that can cause damage, thus extending the duration of use .

6. Check the equipment for damage and debris
Always check that both the hose and quick couplings are in good condition before use. A damaged tube can swell and explode. Damaged equipment must be replaced immediately. Residue deposited on and inside the quick coupler can cause malfunctions resulting in serious injury.

7. Quick couplings with safety function
During disconnection, a conventional quick coupler causes a whiplash of the hose, accompanied by the characteristic burst. A safety quick coupling relieves the downstream pressure before complete disconnection. There will be no whiplash effect and the discharged air will only emit a discreet vent. Safety Quick Connections justify and pay back the investment made to improve worker safety by protecting them from hearing damage and possible injuries upon disconnection, such as bruises.

8. Safety Blowguns for Cleaning
Compressed air is not like ordinary air. Compressed air is condensed and compressed at a higher pressure than the atmosphere. The pressure comes from the air as it tries to return to its original volume. When used, it generates a concentrated flow of high pressure, high velocity air. Even with several layers of clothing, air can penetrate the skin causing serious problems, eg. embolism.
When using compressed air for cleaning it is always a good idea to be sure to do it in complete safety. In the event of a blocked tip of a blow gun, the static pressure in the main port must not exceed 30 PSI (2 bar). When cleaning surfaces, it is important to always use a safety blow gun to prevent compressed air from coming into dangerous contact with your body.

9. Blowguns with safety shield
An effective safety shield prevents chips or particles of any size from being thrown into the operator’s eyes or skin. The protective screen can be either mechanical or through an air barrier; it is possible to choose the best protection according to the applications and the type of debris.

10. Low-noise
blow guns Silenced blow guns must be used where noise exposure exceeds the permitted levels of 85dB (A) within 8 working hours. Employers are responsible for implementing all measures to mitigate the noise level and protect employees from hearing damage.
