SAFETY, HEALTH AND ENVIRONMENT, 2001 9

SafetyPEMEX has achieved significant advances in the

strengthening of industrial safety, as reflected by

the frequency and severity indexes’ downtrend

of the last 6 years. The following are the results

reported in 2001:

• PEMEX’s overall frequency index dropped

17% compared to 2000 (from 1.19 to 1), while

the severity index decreased by 38% (from 170

to 106).

• These figures reveal a substantial contraction;

there was only one disabling accident per more

than 1 million hours worked (1,007,561 man-

hours), which represents a 20% increase in

hours worked per disabling accident compared

to 2000.

• Although statistics show advances, in 2001 PE-

MEX underwent five fatal work accidents.

• Petróleos Mexicanos is executing a deep

technical analysis of each of these accidents to

ascertain their cause, studying all the elements

that can help determine the conditions in which

they occurred in order to take the necessary

measures to prevent future similar accidents.

The safety performance of all the PEMEX

subsidiaries during 2001 compared to the

previous year is shown below:

Pemex Exploración y Producción. Although

it experienced three fatal accidents, its severity

index dropped 44% and its frequency index

fell 26%.

Pemex Refinación. In December, an accident

of considerable dimensions occurred in the Tula

refinery in Hidalgo. However, its severity and

frequency indexes declined, respectively, 33% and

4%, with which it remains as one of the subsidiaries

with the lowest indexes (0.69 frequency and 85

severity).

Pemex Gas y Petroquímica Básica. It has

reported no fatal accidents for the second

consecutive year and its frequency index (0.50,

or a 44% decrease from the previous year)

remains Petróleos Mexicanos’s best. Its severity

index fell from 109 to 88, a 19% reduction.

Pemex Petroquímica. 2001 has been this

subsidiary’s best year in terms of safety. Its

frequency index dropped 50% (from 1.06 to

0.53) and its severity index declined 51% (from

170 to 84), obtaining Petróleos Mexicanos’s

greatest reduction in both indexes.

CASE: REINFORCEMENT OF A CULTURE OF SAFETY IN PEMEX• The company carried out a campaign that included training of floor supervisors and diffusion of postersdescribing the Executive Tower’s risk circumstances and safety features, and five partial emergency drillsfor explosion, fire, and care of injured individuals for an integral management of emergencies.

• The Petróleos Mexicanos Mixed Group for the Coordination of Local Mixed Safety and HygieneCommissions (GMC) operated according to the contractual commitments for the 1999-2001 period.Its function is to coordinate representatives from the Medical Services Sub-Direction, the AdministrativeCenter’s Integrated Services Unit and the Telecommunications Engineering Management —members ofthe GMC.

aSome indexes’ variations from the 2000 report are due toimprovements on the subsidiaries’ databases, including the recentevaluation of partially or permanently disabling accidents which, insome cases, are determined up to two years after they happen.

PEMEX Corporativo

PEMEX Corporativo. Although not

performing industrial activities , corporate

personnel are also exposed to accidents. In 2001,

its frequency and severity indexes rose 25% (1.49

to 1.86) and 66% (32 to 53).

Contractors. In its safety improvement process,

Petróleos Mexicanos continues performing follow-

up on contractors’ safety. In 2001, the contractors’

frequency index rose 37% compared to 2000,

from 1.8 to 2.47.

Petróleos Mexicanos’s safety results in 2001 allow

us to reach two important conclusions:

• The Industrial Safety and Environmental

Protection Management Systems (SIASPA and

PROSSPA) have been successful, achieving

substantial improvements on the accident

indexes and on PEMEX’s overall safety culture.

• The unfortunate personal and industrial

accidents, such as the Tula refinery’s, indicate that

efforts at all levels must be maintained and that

actions to intensify the implementation of SIPA

Management Systems to safeguard personnel

and facilities safety must continue.

RegulationsPEMEX must comply with the Federal Metrology

and Standardization Law —particularly with the

Mexican Official Standards (NOM). According to

this Law, it must issue guidelines for the acquisition,

lease and contract of goods and services.

The Petróleos Mexicanos and Subsidiary

Organizations Standardization Committee was

created in October 1998; in 2001 it issued 19

guidelines that can be consulted at

www.pemex.com, as well as 46 projects for

standards that will become operative in 2002.

Guidelines help suppliers, contractors and other

purveyors of goods and services to comply with

official requirements , in addition to those

determined by the company. They provide a legal

framework in which representatives of the

domestic and international industry participate and

they cover the public consultation requisite

established by law.

PEMEX participates in 14 National Standardization

Consulting Committees and in the teams that

create and review the Mexican Official Standards.

During the First Seminar on Standardization and

Conformity, held in Mexico City in November

2001, the standardization advances on conformity

evaluation and third party certification were

analyzed. As a result of this seminar, the

Committee agreed to hold the First National

Crusade for Standardization and Conformity

Evaluation in PEMEX and its subsidiaries in 2002.

One of SIASPA’s objectives is to provide the PE-

MEX work centers with a complete and updated

standardization framework. To achieve this, the

Corporate Standards Library —which has 22

collections of international regulations available for

consultation— was created.

In addition, general Safety, Environmental

Protection, Quality, Civil Protection and

Occupational Health guidelines have been issued

to prevent risks during the design, construction,

operation, survey, maintenance and decommissioning

of company facilities.
