Operational Guides

Information for decision-makers and operators in the event of a spill of pollutant into an aquatic environment.

Our operational guides provide decision-makers and operators with access to the necessary information required to handle releases in the aquatic environment of pollutants such as oil, litter, chemicals, containers, etc.

These documents address the different stages of spill response, from aerial surveys to waste management, covering issues such as the use of response products, response to containers and packages, not forgetting the local authorities which are required to make quick decisions when a pollutant washes up on their shores.

These guides draw upon Cedre's knowledge developed through the results of studies, experimentation and feedback from incidents. They include information on initial response measures intended primarily for operational response managers.


Aerial Observation

This publication, dedicated to aerial observation, is an update of the guide published in 2009.


The aim of this operational guide is to provide the information necessary for an initial decision to be taken even before any precise information from the shipping companies involved is available.

Custom-Made Barriers

During the response to many oil spills in coastal or inland waters, the use of manufactured booms has often been supplemented by the use of devices put together by response teams in emergency situations.


This guide replaces two others entitled "Manual for treating slicks with dispersants sprayed from surface vessels" and "Manual for treating slicks with dispersants sprayed from airborne assets" dating back to 1987 and 1991 respectively. We update our publications in the light of how techniques, technology and knowledge have developed, in a more operational format. The 2015 update is available in French only, translation is in progress.

Ecological Monitoring

This guide is aimed at decision-makers liable to be involved in designing and implementing ecological monitoring programmes in the aftermath of an accidental water pollution incident.

HNS / Accidental Water Pollution

This guide is an operational document to be used by professional responders in the event of an HNS spill

Local Authorities

The guide addresses some general issues and provides many examples of the French organisation.

This guide aims to give this authority keys to decision-making in the event or threat of a spill of pollutant liable to reach the banks or shoreline of his municipa­lity.


An oil spill in a mangrove can have detrimental effects. This guide presents the main aspects to be aware of and considered for response or to decide not to respond.

Manufactured Booms

This guide focuses on manufactured (i.e. factory-made) spill response booms and attempts to provide an overview of the main models available on the market.

Pollution in Ports

This guide aims to provide operational answers to all the questions which responders may have on the choice of response techniques and materials suitable for small pollution incidents in ports and harbours.

Sea Professionals

The aim of this guide is to provide managers of fleets of sea professionals as well as response operators on the shoreline, with organisational and technical solutions in order to implement an appropriate and efficient response to a spill of pollutant, whether crude or refined oil, chemicals, drums or containers.

Shoreline clean-up

This guide to "Oiled shoreline clean-up" summarizes Cedre's knowledge acquired through various studies and experiments carried out since its creation, as well as during accidents in France and abroad.


This guide is devoted to skimmers designed and marketed specifically for response to spills of floating pollutants. It also covers the related ancillary means which is required to ensure efficient recovery.


The guide is aimed at operators liable to use sorbents as part of response operations to accidental oil or chemical pollution.

Surveying Sites

This guide seeks to present a coastal survey method likely to produce a useable, short and yet complete report that can be used as a basis for filling in an operational coastal report form.

Vegetable Oil

Vegetable oils are an ever-increasing part of bulk traffic. These oils are only slightly toxic, however, when spilled in significant volumes, they can have adverse effects on the environment.

The aim of this guide is to offer useful scientific and technical facts to operational teams.


This guide is aimed at setting out general, common principles of organisation and management in the event of a coastal pollution incident, in particular for associations and NGOs who may have to manage volunteers.

Waste Management

This guide is aimed at people who may have to manage waste following a water pollution incident. This guide reviews the different stages of waste management and their constraints. 

Wildlife Rehabilitation

In addition to covering regulatory and organisational aspects, this guide summarises the practices and protocols to be applied when setting up and operating a temporary wildlife rehabilitation centre. It deals with birds, as well as pinnipeds, otters and turtles.
