(GRI 403-9) (SDGs 3.3, 3.4, 3.6, 3.9, 8.8, 16.1) T: Occupational health and safety Actions taken to eliminate occupational hazards and minimize risks:

Guatemala Hydraulic

The activities performed by the injured person were re-evaluated and the following actions were taken: Changing the safety shoes for ones with better soles for the cleaning activities. The company responsible for pest control was asked to change the oil base used for nebulization to a water base to avoid slippery surfaces. An update training was conducted for all the cleaning staff on the safety measures to perform these activities.

Honduras Wind

A training was carried out to update forest fire-fighting techniques and drill practices, and to create the requirements that must be met by people who want to be part of the forest crews, who participate in fire-fighting. Provide the fire-fighters with personal protective equipment, like helmets for working at heights.

Costa Rica Wind

Staff was trained in risk assessment of the work area, especially looking for irregularities on the ground, to avoid falls or tripping. Thus, the incident reporting procedure was reinforced where it states that when an incident occurs, however simple, it should be reported immediately in order to receive first aid.

Hearing Program at Hydroelectric Power Plants, Energy Business Unit

(GRI 403-3, 403-6) (SDGs 3.3, 3.5, 3.7, 3.8, 8.8) Occupational noise can cause alterations in human hearing and other types of illnesses if adequate control measures are not taken. Our program, for hydropower plant operations in Guatemala, was implemented from 2017. The cases identified are taken as a baseline, since there was no pre-employment baseline, this means that it cannot be assured that employees arrived with injuries or that they were injured in our operations.

Objectives:

1. Prevent and control hearing loss caused by exposure to industrial noise. 2. Implement the necessary control measures for emission reduction

in our operations and noise exposure for our associates.

Program phases:

1. Noise measurement: • Exact noise measurement to identify the equivalent continuous noise level, Lmax and Lpk, of each equipment in the operation. • Review noise exposure during the working day, according to the working positions that are more exposed.

2. Training for associates:

• Trainings planned in the training program. • Specific surveys to assess knowledge of the hazard and methods of protection. • Assessment of personal protective equipment using EAR Fit. Feedback at the moment.

3. Annual Occupational Medical Assessment:

• Medical evaluation to rule out noise-related illnesses. • Audiometry to rule out hearing damage.

Results:

During 2019, all phases of the program and specific control measures were implemented, achieving a reduction in the incidence rate and prevalence of hearing damage among our associates. Efforts are continuing to reduce new cases of hearing damages to zero, related to our operations.
