Work Safely on Powered Platforms

Overview
Performing maintenance work while using a powered platform presents special hazards. One type of hazard is walking and working surfaces where the potential for falls exists.
Maintaining a safe work atmosphere on a powered platform involves proper inspection and maintenance, as well as a thorough understanding of emergency procedures.

How can I protect myself?
Follow the manufacture’s guidelines when operating and using a powered platform. Some basic rules to follow for any type of powered platform include the following:
• Do not exceed the load rating for the powered platform in use. (The load rating is found on the platform load rating plate).
• Clear platforms of ice, snow, and other slippery materials.
• Protect the platform, its components, wire ropes, and lifelines from damage.
• Do not use the platform in winds exceeding 25 miles per hour.
• Use the mounted anemometer to measure wind velocities during the use of the platform.
• Keep the platform free of debris, unused tools, and materials.

Inspection
To ensure the proper operation of a powered platform, competent persons must inspect it at regular intervals. Inspections of a powered platform consist of the following:
• Checking the platform and its components for visual defects in a daily inspection before use.
• Inspecting the building supporting structures for the powered platform on a yearly basis.
• Inspecting all parts of the powered platform according to manufacturer’s guidelines at least yearly.
• Inspecting and testing the governors and secondary brakes according to manufacturer’s guidelines at least yearly.
• Inspecting all suspension wire ropes visually after each use and after each incident that might affect the rope’s integrity.
• Examining all ropes that have not been in service for more than 30 days.

Use a personal fall arrest system
Another factor in safe powered platform work is the use of personal fall arrest systems. A personal fall arrest system limits the fall of a worker from the platform. The personal fall arrest system consists of a full body harness, lanyard, rope grabs, lifeline, lifeline anchorage points, and riggings.
When using a personal fall arrest system, you should know and understand the following items:
• Application limits.
• Proper anchoring and tie-off techniques.
• Deceleration distance.
• Elongation distance.
• Damage.
• Other deterioration.

Recognize the Warning Signs

Overview
In an effort to decrease the number of accidents and injuries in the workplace, OSHA developed two standards on safety color-coding and specifications for accident prevention signs and tags. A sign refers to a surface on prepared for the warning of, or safety instructions of, industrial workers or members of the public who may be exposed to hazards. The information is located in 29 CFR 1910.144 and 1910.145.

What must I know?
There are a few different means of designating signs and tags. Color and shape work well for the purpose of communicating required information. The American National Standards Institute (ANSI) has developed the following color scheme:

Safety colors:
- Red - Fire, danger, or stop
- Orange - Warning
- Yellow - Caution
- Green - Safety
- Blue - Notice

Shapes:
- Triangle - Hazard alerts
- Circle - Mandatory actions
- Square/rectangle - Information
- Circle with slash - Prohibited activity

According to the National Electrical Manufacturer’s Association/American National Standards Institute (NEMA/ANSI), the lettering must be in upper case block letter, and large enough that a person with normal vision can read it. The labels on piping also play a vital role in informing employees and emergency personnel what is contained in the pipes in your workplace. These labels are color-coded and include the substance name.

Labels on piping:
- Yellow - Flammable
- Green - Liquid, non-flammable
- Blue - Gaseous
- Red - Fire quenching material

Adequate lighting should be available for signs so that the message is readable. Your employer strives to maintain the safest workplace possible, and the communication of hazards plays an important role. Knowing the difference between red and green may sound simple, but it could save a life.

Excavation Overview Handout

Trench cave-ins can be prevented. Yet every year there are an estimated 75 to 200 deaths and more than 1,000 lost work days per year from trenching accidents.
What does the competent person look for?
According to OSHA, your company competent person must inspect all excavations each day for evidence of a situation that could result in:
• possible cave-ins.
• indications of failure of protective systems.
• hazardous atmospheres.
• other hazardous conditions.
However, if you work in trenches/excavations you should know much of the same information your competent person does. Why? A sudden change could mean disaster for you and fellow workers.

What are unsafe conditions?
Some of the things that could cause an immediate change at an excavation site are:
• A bulldozer or excavator coming too close to your trench could cause a surcharge (overloading) and stress cracks at or near the edge of the trench.
• A sudden downpour could fill the trench or cause rain-soaked soil to give way.
• Accidently striking an underground utility line with a tool could present an immediate electrocution or hazardous atmosphere hazard.
These are just a few of the sudden incidents that need immediate attention and decision-making. That’s why the OSHA rules require your company to train you in the recognition and avoidance of unsafe conditions, the regulations applicable to your work environment, and to control or eliminate any hazards or other exposure to illness or injury.

What does OSHA's regulation cover?
OSHA’s excavation rules apply to all open excavations made in the earth’s surface including trenches. The regulation is in the construction standards at §1926.650-.652 and covers:

Scope and application—The rule applies to all open excavations made in the earth’s surface. Excavations are defined to include trenches.

Specific excavation requirements—to include surface hazards, underground utilities, getting in and out of the excavation, traffic hazards, hazardous atmospheres, emergency rescue, inspections, and fall protection.

Requirements for protective systems—The rule says each employee in an excavation must be protected from cave-ins by an adequate protective system designed in accordance with the OSHA regulations for:
• sloping and benching systems, or
• support, shield, and other protective systems.

Exceptions would be when:
• Excavations are made entirely in stable rock; or
• Excavations are less than five feet deep and examination of the ground by a competent person provides no indication of a potential cave-in.
• Excavations are one of the most dangerous places in construction work. Your knowledge of the hazards and a constant vigil could make a life or death difference.

Muddy Conditions

With the change from summer to fall usually means the change from dry ground to muddy conditions. Slip and fall accidents are much more likely to happen during these times. Unfortunately we are unable to control the weather, so we must adapt to conditions daily. Simple steps taken can be the difference in preventing an accident.

1. Keep boots free of mud. Employee should clean boots of mud once they reach the house or unit they are to work in. This may have to be done every time you leave and return. No employee should access top plates or roofs if their boots are muddy.

2. Keep ladders free of mud. If you are using a ladder in mud, tracking mud up the rungs of the ladders creates a very slippery and dangerous condition. Employees should use the bottom rung to scrap mud from there boots. If mud does accumulate, you may need to take a rag or towel and clean the rungs.

3. Walk in areas were stone driveways/paths have been provided. If a stone path is not provided, you may want to use some plywood or planks to create a walkway to the work area.

4. Store material/lumber close to the house to minimize having to walk in the mud to reach piles or stacks.

5. Move slowly – don’t be in a rush. Carrying material or equipment through mud could cause you to slip. Several strains and sprains have been cause as the result of a slip.
