Why Signalpersons And Spotters Are Essential To Safe Mobile Crane Operation
It can be easy for those who have never rented a crane before to think that a crane rental comes with just the machine and an operator. Due to the inherent dangers posed by poorly managed lifts, however, crane rentals involve a number of other personnel to ensure the safety of everyone on site.
When you rent a crane, the rental business should provide you with qualified personnel covering the following roles:
- Crane Operator
- Signaler
- Dogmen
- Riggers
Your crane rental company will also take responsibility for safe crane erection and maintenance throughout your rental period. But these are the personnel you will be working with onsite. Each provides a crucial part of safe and efficient operation.
In this article, let’s take a look at signalers and spotters specifically, their jobs required qualifications, and just why they are essential to ensuring your job site is safe.
The Role Of Signalpersons And Spotters On The Job Site
Proper communication is the key to safety throughout crane operation, especially while a lift is in process. There may be times when the crane operator does not have a direct line of sight of the load. In those times, they rely on trained signal-callers, often referred to as either signalers, signalpersons, or spotters.
Construction sites can be incredibly loud, and you shouldn’t depend on verbal communication, even over the radio. These personnel have received training on quick, clear communication to and from crane operators and know what hazards to watch for during lifts. It's their job to watch the entire lift zone and help mitigate known hazards and emergencies.
Safety should be a top priority, especially when heavy machinery such as cranes is in use on-site. According to the U.S. Bureau of Labor Statistics, from 2011 to 2017, there was an average of 42 deaths a year involving cranes. No project is worth someone’s life, so it is critical that you regularly review your safety training and standards.
Training And Required Qualifications
All signalers and operators receive training using OSHA standard hand signals to ensure that there is no confusion between personnel while a crane lift operation is underway. A signal person on-site has a dedication to providing communication between all members of the crane operation.
The National Commission for the Certification of Crane Operators (NCCCO) provides a certification course for individuals to become qualified signalperson. This qualification process includes a written and practical exam that covers:
- Standard OSHA hand signals
- Voice communication methods
- Basic knowledge of crane operations
- Site and hazard awareness
- Safety standards and regulations
The best tools for safely operating a crane are experience, communication, and proper training. Whether you are renting or operating your own crane, make sure your personnel have the required level of training.
Standard Communication Methods
If you plan to have a crane on-site for an extended period, we recommend getting your regular, non-crane crew up to speed on these hand signals so they can safely navigate around the lift area. Take a look at some of the common hand signals used in crane operation, and review them to make sure your crews haven’t been using any incorrectly on site.
Some common hand signals to be aware of include:
- Stop: With the arm extended horizontally to the side, palm down, the arm is swung back and forth.
- Raise Boom: With the arm extended horizontally to the side, the thumb points up with the other fingers closed.
- Lower: With arm and index finger pointing down, hand and finger making small circles.
- Emergency Stop: With both arms extended horizontally to the side, palms down, arms are swung back and forth.
If it seems like your crew has been using non-standard signals, take preventative steps to bring them in line with OSHA standards before you get a crane on site to reduce any confusion or potential conflicts.
