set process of safety steps undertaken as part of a road 

transport journey, particularly one that involves driving for 

several hours.

Maximum driving time between breaks: Light vehicle 2h heavy vehicle 4 hours; Minimum break time mins

Medical: ＜40,3years

                      40-50,2years

                      ≥50，1year

What's Fog level: 100 meter

8. PPE(welding shield, Respiratory mask, leather gloves, leather clothes, long safety shoes)

3.        Lifting Work:

1.PTW

2.A third-party certificate of equipment and riggers(crane and lifting gears)

3. Crane checklist will be filled by the Operator (Park on the level and solid firm ground, outriggers have fully extender, wooden plate, no hydraulic leakage.)

4. Buried the lifting area and signboards to be placed(under boom radius)

5. Lifting plan.

others:

The safety device of crane:

1. Anti-two block

2. Safety latch

3. Spirit level

4. LMI-Load Movement Indicator(anemometer, overload、complete control of crane)

5. swinging alarm

   How many types of lifting?

1. Normal lifting

2. Critical lifting

3. Heavy lifting

Once wind speed exceeds 17 knots, lifting activity shall be stopped.

3.1. Name of three potential hazards associated in lifting activity and what is colour coding?

 Ans.: Fall of load or equipment personnel/facility struck by load/ equipment, weather conditions (sand storm, wind speed (stop lifting at a wind speed of 17 knots).

Colour coding: colour-coding means that instruments are in good condition with third-party certification.

Visually inspection with third-party certification. All things are good at putting one identification on that instrument.

3.2 How you know that crane can lift this much of tones in this radius?

Ans.: By checking Load chart

4.        Excavation:

What is excavation what is the difference between trench and excavation?

Excavation is a process of moving or digging earth rocks or other materials at ground manually or with mechanical equipment.

Excavation as any man-made cut, cavity, trench, or depression in the earth's surface formed by earth removal.

The trench is defined as a narrow underground excavation that is deeper than it is wide, and is no wider than 4.5 meters.

Access every 5meters (15-20 feet).

Excavation PTW requirements?

1. PTW

2. Excavation Certificate

3. Area scanning report by the surveyor and signed by HSE

4. A third-party certificate of equipment and banks man.

5. Check the soil, if loose, sloping, benching and shoring

6. Barricade the excavating area and put safety signs (more than 1.2 hard barriers)

7. Keep 1-meter edge clear

Others:

Controls?

1)      Shoring, 2) Shielding, 3) Sloping, 4) Benching.

Type of soil and How much angel to be provided for sloping:

       Stable Rock -90 degree.

Type A- 53 Degree slope to be maintained for sloping

Type B-45 Degree slope to be maintained for sloping

Type C-34 Degree slope to be maintained for sloping

4.1What are the Main hazards in Excavation activity?

Ans.: Underground utilities, Collapse of excavation wall/Cave in, limited access and egress, presence of toxic gases, falling of person, falling of vehicle, falling object on the person whoever working in an excavation. Adverse weather

4.2.  What are the safety precautions for excavation?

Trenching and Excavation Rules

Ans.:

• Keep heavy equipment away from trench edges at least 3 meters.
• Keep surcharge loads at least 1 meter from trench edges.
• Know where underground utilities are located.
• Test for low oxygen, hazardous fumes and toxic gases.
• Inspect trenches at the start of each shift.
• Inspect trenches following a rainstorm.
• Do not work under raised loads.
• Provide proper shoring benching or sloping where required.
• Provide proper hard barricading which is visible from distance.
• Provide proper safety signage boards.
