THE PREGNANCY FOR WORK

• Performs agricultural work mechanized: ploughing, preparation of the seedbed (discus, scarified), sowing, crop maintenance (sowing), fertilized, herbicided and freeing the land of plant residues.

• Drive, maneuver and operates tractors, agricultural machinery and assemblies tractor-trailer, both in the premises and on the agricultural lands, as and on access roads or public roads, as the case may be.

• Jet of oil (p>100 bar.) upon accidental cracking of the hydraulic installation

• cutting, stinging on contact with dangerous surfaces.

• Containers under pressure (air cylinder, trailer cylinders).

• Vibrations excessive movements of the machines when moving on uneven ground (missing suspension).

• FACTORS THERMAL RISK

• Burn thermal damage caused by the contact of the epidermis with splashes, sparks, slag, high temperature surfaces (welding beads, recently welded parts etc.)

• Temperature lowered of the parts it comes into contact with when working in the air free in the cold season.

• flames, flame – thermal burn, electric arc.

• FACTORS ELECTRICAL RISK

• Electrocution by indirect touch during repair operations (from electrically operated devices).

• FACTORS CHEMICAL RISK

• The thing with flammable substances - fuels (diesel), oils, grease

2. THE ENVIRONMENT FOR WORK

   • FACTORS OF PHYSICAL RISK

• Temperature high air in the warm season.

• Temperature low air in the cold season.

• Currents of air - non-sealing cabin (U 650).

• Noise constant with some short-term exceeding of the value of 87 dB(A).

• Powders pneumoconiogenic (dust) when moving on the road, tipping, etc.

• FACTORS CHEMICAL RISK

• The clearance of gases, toxic vapors resulting from the use of the products phytosanitary.

• gases, toxic vapors specific to the welding process etc.

• FACTORS OF BIOLOGICAL RISK

• Microorganisms in suspension in the air, from the vegetable products that manipulate.

• The presence dangerous animals and insects: rats, dogs, wasps

3. THE PREGNANCY FOR WORK

   • REQUEST PHYSICS

• Effort dynamically when handling the steering wheel (inefficient power steering - U 650) and static stress caused by the lack of suspension.

• REQUEST PSYCHIC

• Attention requested to the maximum for driving on the public road or by access, at low speed and under stress (noise, vibrations etc.).

4. WORKER

   • ACTIONS WRONG

• Execution of dangerous manoeuvres: without visibility, with unsuitable speed the work, when moving on the slope or on the level curve, when turning with trailer coupling

• identification, by smelling, of the existence of the acetylene flow at the light bulb welding.

• The use of unsuitable or broken, opaque light filters etc.

SHEET OF PROPOSED MEASURES FOR THE JOB

INTERPRETATION

RESULTS ASSESSMENTS FOR

THE POST FOR WORK

The calculated global risk level for the job is equal to 3,13, value that places it in the category of jobs with risk level unacceptable.

The result is supported by "Evaluation sheet ”, from which it can be seen that from the total of 57 identified risk factors (Fig. ­1 ), 6 exceed, as a partial level of risk, value 3: 0 falling into the category of risk factors maximum, 0 falling into the category of risk factors very big, 0 falling into the category of risk factors big, again the others 6 falling into the category of medium risk factors.

Those 6 risk factors that are in the unacceptable range are:

For diminishing or eliminating those 6 risk factors (which are in the unacceptable range), are necessary measures generically presented in "Measures sheet proposed” for the job

In regarding the distribution of risk factors by source generators, the situation is as follows (see Fig. 2 ):

• 31,58%, own factors means production;

• 15,79%, own factors the environment of work;

• 3,51%, own factors the pregnancy of work;

• 49,12%, own factors the worker.

From the analysis Evaluation sheets it is found that 73,68% among the identified risk factors may have consequences irreversible on the worker (DEATH or DISABILITY)
